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

Neovascular age-related macular degeneration (AMD) and polypoidal choroidal vasculopathy (PCV) are leading causes of irreversible blindness in developed countries. In this study, we investigated the associations of haplotype-tagging single nucleotide polymorphisms (SNPs) in the complement component 3 (C3) gene with both neovascular AMD and PCV, and potential epistatic effects on C3. Eight tagging SNPs in C3 were genotyped in 708 unrelated study subjects: 200 neovascular AMD patients, 233 PCV patients and 275 controls. Among the eight C3 SNPs, rs17030 was associated with PCV after adjusted for gender and SNP-gender interaction (P = 0.008, OR = 2.94; 95% CI: 1.32-6.52). Moreover, an interaction between rs17030 and gender was identified in PCV (P = 0.02). After stratification by gender, the rs17030 G allele was found to confer an increased risk for PCV in male (P = 0.010, OR = 1.56) but not in female. The haplotype AG defined by the major alleles of rs17030 and rs344555 was also associated with PCV in male (P = 0.010, OR = 0.64). In contrast to PCV, none of the eight SNPs was significantly associated with neovascular AMD. This study shows an association of C3 rs17030 with PCV in male, indicating that C3 may have an epistatic effect with gender in the pathogenesis of PCV.
