Figure A9.

Meta-analysis on prenatal supplementation of branched chain amino acid on fetal/birth weight (BW): Prenatal branched chain amino acid supplementation did not affect birth weight, neither in normal-growth pregnancies nor in complicated pregnancies. Data are ordered within each amino acid (AA) from smallest to largest animal. Data represent pooled estimates expressed as a ratio of means (ROM) with a 95% confidence interval (CI) using a random effect model. Residual I² is shown. Some studies had multiple cohorts and are distinguishable in this figure by the following: * in this upper line, the daily dose is lower compared the next line(s) in increasing order; † the upper two lines are in the lower dose compared to the next two lines, and per dose, the outcomes are separately reported for males first and then females. FGR, fetal growth restriction; I², heterogeneity.
