Integrin α2 gene polymorphism is a risk factor of coronary artery lesions in Chinese children with Kawasaki disease.

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
backgroundKawasaki disease (KD) is a systemic vasculitis, and the formation of coronary artery lesions(CAL) is its most common sequela. Both genetic and environmental factors are considered to be important factors of in KD. Integrin α2 (ITGA2) is a transmembrane receptor that is associated with susceptibility to several diseases, but its relevance to KD with CAL is unclear.
methodsWe genotyped ITGA2 rs1126643 in 785 KD patients with the CAL and no-CAL(NCAL) (300 patients with CAL, and 485 age- and sex-matched patients with NCAL). OR (95% CI) and adjusted OR (95% CI) were used to evaluate the intensity of the association.
resultsWe found a significantly increased risk of KD with CAL associated with ITGA2 rs1126643 genotypes (CT vs CC: adjusted OR = 1.57, 95% CI = 1.16-2.12, P = 0.0032; CT/TT vs CC: adjusted OR = 1.49, 95% CI = 1.12-2.00, P = 0.0068; T vs C: adjusted OR = 1.66, 95% CI = 1.16-2.51, P = 0.0165). Moreover, we found that carriers of the CT/TT genotype had a significant risk of KD with coronary artery lesion susceptibility for children ≤60 months of age, and the CT/TT genotype was significantly associated with an increased risk of SCAL formation and MCAL formation when compared with the CC genotype.
conclusionITGA2 rs1126643 was associated with increased susceptibility and severity of CAL in KD.
