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

A possible role of Snap25 polymorphisms in type 2 diabetes mellitus (T2DM) was evaluated by analyzing three SNPs within intron 1 in a region known to affect the gene expression in vitro. Genomic DNA from 1019 Saudi individuals (489 confirmed T2DM and 530 controls) was genotyped for SNPs rs363039, rs363043, and rs363050 in Snap25 using the TaqMan Genotyping Assay. Significantly higher levels of fasting glucose and HbA1c were detected in T2DM patients carrying the rs363050 (AG/GG) genotypes compared to the (AA) genotype (f = 4.41, df = 1, and p = 0.03 and f = 5.31, df = 1, and p = 0.03, resp.). In these same patients, insulin levels were significantly decreased compared to the (AA) individuals (f = 7.29, df = 1, and p = 0.009). Significant associations were detected between rs363050 (AG/GG) genotypes and increasing fasting glucose levels (p = 0.01 and OR: 1.05), HbA1c levels (OR: 5.06 and p = 0.02), and lower insulinemia (p = 0.03 and OR: 0.95) in T2DM patients. The minor Snap25 rs363050 (G) allele, which results in a reduced expression of Snap25, is associated with altered glycemic parameters in T2DM possibly because of reduced functionality in the exocytotic machinery leading to suboptimal release of insulin.
