Association of Interleukin-31 gene polymorphisms with risk of cryptorchidism in a Chinese population.

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.
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
This study aims to investigate the possible association between Interleukin-31 (IL-31) gene polymorphisms and cryptorchidism risk.Two single nucleotide polymorphisms of IL-31, rs7977932 (C/G) and rs4758680 (C/A), were selected to be investigated in this study. Polymerase chain reaction-restriction fragment length polymorphism methods were used to discriminate the selected single nucleotide polymorphisms of IL-31 gene. A hospital-based case-control study of 112 cryptorchidism patients and 425 healthy controls was conducted.The frequencies of the C allele of rs4758680 in the patients with cryptorchidism were significantly higher compared with those in controls (89% vs 83%, P = .02, OR = 0.58, 95% CI = 0. 37-0.92). Compared with CC genotype in dominant model, notable decreased frequencies of A carriers (CA/AA genotypes) were observed in cryptorchidism patients (P = . 03, OR = 0.58, 95% CI = 0.35-0.96).Results demonstrated that IL-31 gene polymorphisms were associated with the genetic susceptibility to cryptorchidism in a Chinese population. Compared with CC genotype, the A carriers (CA/AA genotypes) of rs4758680 were protect factors in cryptorchidism susceptibility.
