Synopsis

The synopsis of this outcome is based on the same systematic review described under preeclampsia. The overall effects of calcium supplementation were not significant (among three RCTs in 13,091 randomized women RR = 1.10, 95% CI 0.88, 1.37). (Included in this meta-analysis are the two large trials mentioned in the preeclampsia section, which found no significant effects.)

Based on the above, there is no evidence for an effect of calcium supplementation on preterm births.
