Fig 5.

Analysis of associations between temperature and outcome by age of women during pregnancy. Purple shading indicates period of highest risk in studies that analysed with multiple age categories. Orange shading indicates studies with age as a binary variable, limiting the assessment of risk period. Data on whether differences between subgroups were significant were not provided for most comparisons. Only studies that showed a significant association between temperature and the outcome are included. ^*Only in Rome, one of six sites in the study. Study details are given in supplementary tables 2a, 2b, and 2c
