  1. Data is presented as quantile regression estimates and 95% confidence intervals (CI) of birth seasons for the 25th, 50th, 70th and 90th quantiles of birth outcomes (n = 190). Adjusted for maternal age, household assets, maternal education (yes vs no), interview season, total duration of pre-harvest season during pregnancy and maternal energy intake. *P < 0.05, **P < 0.01
