Forest Plot from Scientific Research

Pooled ORs capturing the association between lockdown and the odds of spontaneous preterm birth, stratified by month of lockdown, type of data (population-based, non-population based) and income setting. Pooled ORs (represented by boxes on plot) were calculated using random-effects meta-analysis. Horizontal lines surrounding each box on the forest plot are 95% CIs for the OR. Arrows indicate upper and/or lower bounds of the CI that are outside the x -axis limits. NA, not applicable.
