Revisiting the link between NADPH oxidase p22phox C242T polymorphism and ischemic stroke risk: an updated meta-analysis.
Article in Open life sciences, 2025. 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
The relationship between the NADPH oxidase p22phox C242T and susceptibility to ischemic stroke (IS) has been extensively studied, yet the findings from these studies remain inconsistent. To clarify this association, we conducted an updated meta-analysis of case-control studies. A comprehensive literature search of PubMed, Embase, and CNKI was performed on January 31, 2025. Studies exhibiting Hardy-Weinberg equilibrium (HWE) deviations in the control population were excluded from analysis. Pooled odds ratios (ORs) with corresponding 95 % confidence intervals (CIs) were calculated to evaluate the association across various genetic models. Our meta-analysis included 10 studies, comprising 3,422 cases and 3,410 controls. We found no significant association between the C242T polymorphism and IS susceptibility under any genetic model. Subgroup analyses stratified by ethnicity and IS type similarly revealed no significant increase in risk. Sensitivity analysis confirmed the stability of these pooled results. This updated meta-analysis suggests that the NADPH oxidase p22phox C242T polymorphism lacks a significant association with ischemic stroke risk. Nevertheless, larger and more diverse population studies are warranted to confirm these findings.
