Fig. 3: Association between per IQR of PM2.5 components concentrations with an interaction of birth weight status and health outcomes such as anaemia and ARI.

The odds ratios with their 95% confidence intervals are represented in black dots with error bars. LBW represents low birth weight; NBW represents normal birth weight. The analytical sample size used for each health outcome is provided in the consort diagram (Supplementary Fig. 1).
