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

backgroundMounting evidence has suggested that tumor necrosis factor-alpha (TNF-α) can promote the development of diabetic retinopathy (DR), and TNF-α gene variants may influence DR risk. However, the results are quite different.

objectivesTo comprehensively address this issue, we performed the meta-analysis to evaluate the association of TNF-α-308 G/A and -238 G/A polymorphism with DR.

methodData were retrieved in a systematic manner and analyzed using STATA Statistical Software. Crude odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the strength of associations. Allelic and genotypic comparisons between cases and controls were evaluated.

resultsFor the TNF-α-308 G/A polymorphism, overall analysis suggested a marginal association with DR (the OR [95% CI] of [GA vs. GG], [GA + AA] vs. GG, and [A vs. G] are 1.21 [1.04, 1.41], 1.20 [1.03, 1.39], and 1.14 [1.01, 1.30], respectively). And the subgroup analysis indicated an enhanced association among the European population. For the TNF-α-238 G/A polymorphism, there was a mild correlation in the entire group (the OR [95% CI] of [GA vs. GG] is 1.55 [1.14, 2.11]), which was strengthened among the Asian population.

conclusionThe meta-analysis suggested that -308 A and -238 A allele in TNF-α gene potentially increased DR risk and showed a discrepancy in different ethnicities.
