  "summary_technical": "NICE HealthTech guidance HTG630, published 27 July 2022 as diagnostics guidance DG49 and later moved to the HTG number. The Overview page says the recommendations and content were not changed by the move. Recommendation 1.1 covers PlGF-based tests added to the usual clinical examination for people with suspected preterm pre-eclampsia between 20 weeks and 36 weeks 6 days of pregnancy. Whether a later NICE edition replaces it was not checked. Because of NICE's reuse terms, this atlas states the facts in its own words, with a citation and a link.",
