Figure 2

Relative risks of low birth weight/IUGR/SGA according to maternal caffeine intake. Low caffeine intake: 50 to 149 mg/day; moderate caffeine intake: 150 to 349 mg/day; high caffeine intake: ≥350 mg/day. Black dots indicate study-specific effect estimates, sizes of the grey squares correspond to the weights of the studies, horizontal lines indicate 95% CIs, and diamonds indicate the summary estimates with their corresponding 95% CIs. CI, confidence interval; IUGR, intrauterine growth restriction; SGA, small for gestational age.
