A meta-analysis of risk of pregnancy loss and caffeine and coffee consumption during pregnancy

·         PubMed was searched for reports published before September 2014, with the keywords “caffeine,” “coffee,” “beverage,” “miscarriage,” “spontaneous abortion,” and “fetal loss.”

·         Case–control and cohort studies were included when they had been reported in English, the exposure of interest was caffeine/coffee consumption during pregnancy, the outcome of interest was spontaneous abortion or fetal death, and multivariate–adjusted odds ratios (ORs) or risk ratios were provided or could be calculated.

·         Data were extracted and combined ORs calculated.
