Reference datasets of the growth engine

Each dataset defines reference, axis, sex, measure, unit and LMS parameters; from these the same engine calculates z-score and percentiles. The numbers are available as JSON at data/growth/, its origin is stated here and in every file.

Third generation of the Fenton curves (meta-analysis excluding children with abnormal fetal growth). The LMS values meet the official birth weight cutoffs from 2025 to 37 weeks to ≤ 1 %; from 38 weeks, the growth curve deliberately differs from the size-at-birth table (Calgary: “size-at-birth values differ from the growth charts > 36 weeks”). For classification at birth, completed weeks and the cutoff table are decisive; for follow-up monitoring, the exact postmenstrual age.
