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

Vitamin D receptor (VDR) plays a key role in calcium metabolism, and is closely related to urinary stone formation (urolithiasis). Previous studies have investigated the associations between VDR single nucleotide polymorphisms (SNPs) (polymorphisms at BsmI, ApaI, FokI, or TaqI cutting sites) and urolithiasis in different populations. However, the results remain inconsistent and controversial. Therefore, meta-analysis was performed to evaluate these associations. Twenty studies that investigated the associations between VDR SNPs and urolithiasis were retrieved. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated under the most appropriate genetic model. The TaqI polymorphism was associated with an increased risk of urolithiasis (tt + Tt vs. TT: OR = 1.253; 95% CI = 1.033-1.520, p = 0.022, I(2) = 0), whereas the ApaI, BsmI, and FokI polymorphisms were not. Stratifying for ethnicity, a slightly increased risk was found among Asians as compared to Whites (OR 1.263, 1.232, respectively, p < 0.01). Deviation from Hardy-Weinberg equilibrium (HWE) was the major source of heterogeneity. In summary, this updated meta-analysis suggests the TaqI polymorphism is associated with urolithiasis risk, whereas BsmI, ApaI, and FokI polymorphisms are not.
