1 · What the graph read from it

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.

2 · The registry

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

Recent studies have reported the association between endothelial nitric oxide synthase (eNOS) gene G894T polymorphism and pregnancy-induced hypertension (PIH). However, the results have been inconsistent. We conducted a comprehensive meta-analysis to explore this association. A total of 36 case-control studies involving 4028 PIH cases and 7672 controls were ultimately included. In the overall analysis, no association was identified between eNOS gene G894T polymorphism and PIH risk in any of the genetic models. In the subgroup analysis, the results showed that T-allele carriers had a higher risk of PIH than those with the G allele in Asians (G vs. T: odds ratio (OR)=0.76, 95% confidence interval (CI)=0.63-0.91, P=0.002; GT+TT vs. GG: OR=1.32, 95% CI=1.09-1.59, P=0.004; TT vs. GT+GG: OR=1.96, 95% CI=1.26-3.06, P=0.003; TT vs. GG: OR=1.99, 95% CI=1.27-3.11, P=0.003; GT vs. GG: OR=1.23, 95% CI=1.05-1.43, P=0.009). For Latin American and African populations, the association between G894T polymorphism and susceptibility to PIH was only observed in the dominant model. However, no association was observed in Europeans and Americans. Therefore, eNOS gene G894T polymorphism was related to PIH risk, especially for Asians.
