Convert INTERGROWTH z-scores/centiles to fetal ultrasound measurements

Description

Convert INTERGROWTH z-scores/centiles to fetal ultrasound measurements

Usage

igfet_zscore2hccm(gagedays, z = 0)

igfet_zscore2bpdcm(gagedays, z = 0)

igfet_zscore2ofdcm(gagedays, z = 0)

igfet_zscore2accm(gagedays, z = 0)

igfet_zscore2flcm(gagedays, z = 0)

igfet_centile2hccm(gagedays, p = 50)

igfet_centile2bpdcm(gagedays, p = 50)

igfet_centile2ofdcm(gagedays, p = 50)

igfet_centile2accm(gagedays, p = 50)

igfet_centile2flcm(gagedays, p = 50)

Arguments

gagedays	gestational age in days
z	z-score(s) to convert
p	centile(s) to convert (must be between 0 and 100)
