Cumulative evidence for the association between maternal hypertension and cleft lip and palate in offspring: a systematic review and meta-analysis.
Review in Frontiers in oral health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: Maternal hypertension has serious maternal and neonatal consequences. Evidence regarding the relationship between maternal hypertension and cleft lip and palate in offspring is limited and inconsistent. Therefore, we conducted a meta-analysis to evaluate the relationship between maternal hypertension and the risk of cleft lip and palate in offspring. Methods: We systematically searched the following English electronic databases to identify relevant observational studies for our analysis: PubMed, Cochrane Library, Embase and Web of Science, supplemented by a manual reference researches. Study screening, data extraction, and risk-of-bias assessments were conducted independently by two researchers. A meta-analysis was performed using Stata 18.0 and Revman 5.3. Heterogeneity (I Results: The meta-analysis ultimately included 12 eligible studies, comprising 4,407,254 participants. Under the random-effects model, the analysis indicated an association between maternal hypertension and cleft lip and palate in offspring [OR = 1.44, 95% CI = 1.26, 1.64, Conclusion: With our meta-analysis, we provide evidence for an association between maternal hypertension (particularly gestational hypertension and preeclampsia) and CLP in children. Given that residual confounding cannot be entirely excluded, caution is warranted in interpreting the conclusions of this study. More high-quality studies are needed to establish whether the association with maternal hypertension is causal. Systematic Review Registration: PROSPERO CRD420251152806.
