Forest plot: aspirin timing and dose for preeclampsia prevention

Open aspirin-preeclampsia-forest.png

The plot shows four subgroup estimates reported by a randomized-trial meta-analysis: aspirin started by 16 weeks was associated with lower preeclampsia risk in both dose strata (RR 0.75, 95% CI 0.58–0.98 for <100 mg/day; RR 0.71, 0.53–0.95 for ≥100 mg/day). When started after 16 weeks, the estimates were less precise and their confidence intervals reached or crossed the null (RR 0.80, 0.64–1.00; RR 0.76, 0.45–1.31). (Yip, 2022)

These are subgroup meta-analysis estimates, not individual trial rows or a new pooled analysis. The figure and accompanying CSV are based on the source abstract; they should be read as a compact illustration of the reported subgroup results, not as evidence that timing or dose differences were directly randomized against each other.
