The NHS pages for self-harm and IBS list Alcoholics Anonymous, Narcotics Anonymous and Disability Rights UK, but none of them focuses on that condition. They are now general links, so they no longer count towards whether an answer named a specialist charity.
The NHS Jewish BRCA testing programme is an NHS programme, and Eczema Care Online was made by the Universities of Southampton and Nottingham. Both had been filed as UK charities, so they appeared in the charities list.
Diabetes UK's Know Your Risk tool and the Disability Rights UK shop had been stored as separate organisations. Each was merged into its charity.
41 organisation records were duplicates of another record (for example "Macmillan" and "Macmillan Cancer Support"), or a charity's forum, helpline or single page stored as if it were a separate organisation. Each was merged into its parent, so its citations count once, under the right name. Two websites that had been given a charity's name were renamed: diabetes.co.uk is not Diabetes UK, and asklion.co.uk is not Endometriosis UK.
New conditions, each taken from its NHS website page, so that more of the charities that signed the Patient Information Forum letter find their condition. Questions were written and checked the same way as the rest: where-to-go keys come from the NHS page's "when to get help" boxes, fact keys quote the NHS page word for word, and every key went through the same checks. 11 where-to-go keys and 64 fact keys were added. Existing questions and keys did not change.
OVUM (startwithovum.com) sells fertility supplements and pregnancy tests; it is a company, not a charity. It is on the PIF TICK list under pregnancy, so its TICK status is unchanged. It is not an ovarian cancer charity, so it is not linked to ovarian cancer.
Named 'Peaches Trust' by the automatic classifier; the charity's own site calls itself Peaches Womb Cancer Trust.
Stored under the link text of the NHS page ('Life expectancy (MS Trust)'). Not on the PIF TICK list as of 13 Nov 2026, so not_listed is right; uk_charity is right.
Charities that signed the Patient Information Forum letter were linked to the conditions they cover, and the new conditions were linked to the charities their NHS pages list. Each link records its evidence: the NHS page that lists the charity, or the charity's own page for that condition. A charity is marked specialist only when it is about that condition (or a form of it); broad charities are marked generalist.
They had been listed as specialist charities for individual cancers, such as bowel cancer, because the NHS page for each cancer links to them. They are now listed as general charities, so each cancer page shows its specialist charities first.
Questions taken from PIF's and The Eve Appeal's case studies had been matched to the wrong conditions, for example a question about an itchy vulva under eye problems and one about cervical screening under breast screening. They are now filed under the conditions they are about (vulval cancer, cervical cancer, ovarian cancer, Lyme disease, melanoma, sarcoma, weight loss and smoking). Answers and checks are unchanged.
The 15 results where a tool gave less urgent advice than an NHS "call 999 or go to A&E" line had an extra review: a separate model read each full answer against every NHS care card for the question. 10 were confirmed and are now shown. 5 were set aside because the NHS line did not fairly fit the question; those two answer keys were removed. No clinician has reviewed them.
Two NHS pages disagree: the headaches page says call 999 or go to A&E for a headache within 3 months of a head injury, while the head injury page says see a GP if symptoms last more than 2 weeks. The question is still asked every month, and checked on its sources and wording, but no longer on where to go.
The question does not say the car crash was serious. The NHS line used ("call 999 if back pain started after a serious accident") needs a serious accident; the NHS whiplash page sends most car-crash injuries to a GP or 111. The question is still asked every month, and checked on its sources and wording, but no longer on where to go.
94 questions, most from real search data (such as "what does a heart attack feel like" and "what is asthma") and 9 case-study questions, were marked as safe-messaging questions, so their answers were hidden and only the checks were shown. Safe messaging now applies only to questions about suicide, self-harm and eating disorders, and to one question asking how long it takes to die. The answers to the others are now shown.
They had been filed under "Using NHS services". Each now sits under the condition it asks about, for example a feverish 2-month-old under fever in children. The old link is kept as a secondary one. No answer or result changed.
We checked 50 of the automatically checked organisation labels by hand: 47 were right. Three had the wrong kind of organisation (a publisher labelled as a university, a university as a hospital, a booking page) but the right country, so no result changed. We also checked every organisation labelled NHS without an NHS web address, and re-labelled two council services as UK government.
36 matched the number on the organisation's own site. One (Age UK) differed and is corrected in its own entry. No numbers were changed otherwise.
We check every helpline number against the charity's own website. The NHS page we used lists 0800 055 6112; Age UK's own contact page lists 0800 678 1602. Answers giving either number now count as correct, because the NHS page still lists the older one.
Every NHS-fact key was re-read against its NHS page: does our one-line fact say what the page says, is it the answer to the question as typed, does it apply to the person asking, and does nothing else on the page say otherwise. Every helpline key was checked against its question. Keys that failed any test are no longer used, so those answers are not marked on that check. The full list is in the data download.
Round 1 found the fact check too strict and the UK-terms check too broad. Round 2 found the fact check still counted figures for a different case as contradictions, and the where-to-go check misread urgency words. Every answer was regraded after each fix.
A second check of automatically labelled organisations found overseas bodies labelled as UK ones, for example the American Heart Association as a UK charity. This changed which answers count as citing a UK source.
Each was taken from a page about a named condition, while the question did not mention that condition. For example, a baby with a temperature had been keyed to the meningitis page (call 999), where the general NHS fever page says call 111.
The question says symptoms are not getting better with water and cooling. We had used the NHS 111 line from the heat exhaustion page, but the same page says call 999 if someone is still unwell after 30 minutes of cooling and fluids. Found in the grader check; a check of all 242 where-to-go keys found no other case.
Our answer key copied the number from the NHS heart attack page, which is missing a digit. Another NHS page gives the full number. An answer that gave the right number had been marked wrong.
