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

objectiveDiabetic nephropathy and retinopathy are two important microvascular diabetes complications with a high concordance rate in diabetic patients. A recent genome-wide association study in type 1 diabetic patients of European descent identified four loci to be associated with diabetic nephropathy. The aim of this study was to test the effects of single nucleotide polymorphisms (SNPs) from these four loci on diabetic nephropathy and retinopathy in Chinese type 2 diabetic patients. RESEARCH DESIGN AND

methodsIn stage 1, we recruited 1,276 type 2 diabetic patients, including 378 patients with diabetic nephropathy but no retinopathy, 374 patients with diabetic retinopathy but no nephropathy, 244 patients with both diabetic retinopathy and nephropathy, and 280 control subjects with diabetes for >10 years and no diabetic retinopathy or nephropathy. Fifty-five SNPs from four loci (CPVL/CHN2, FRMD3, CARS, and IRS2) were genotyped. The SNPs that showed associations to diabetic retinopathy or nephropathy were genotyped in stage 2 samples for replication.

resultsSNPs from CPVL/CHN2 and FRMD3 were associated with diabetic retinopathy with rs39059 and rs10868025 as the top SNPs (odds ratio [OR] 1.292, 95% CI 1.097-1.523, P = 0.0022, for rs39059; 1.201, 1.014-1.422, P = 0.0343, for rs10868025) in stage 1 samples. In stage 2 analysis, only rs39059 showed similar effect to diabetic retinopathy (OR 1.269, 0.989-1.628, P = 0.0689), and meta-analysis showed a significant association between rs39059 and diabetic retinopathy, with an OR of 1.285 (1.120-1.474, P = 0.0003). CPVL/CHN2 rs39059 was also associated with levels of diabetic retinopathy (P = 0.0007 for trend). However, no association was detected between these SNPs and diabetic nephropathy.

conclusionsIn this study, we found CPVL/CHN2 rs39059 was associated with diabetic retinopathy in the Chinese type 2 diabetic patients.
