Responsible genes in children with primary vesicoureteral reflux: findings from the Chinese Children Genetic Kidney Disease Database.
Article in World journal of pediatrics : WJP, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
backgroundPrimary vesicoureteral reflux (VUR) is a common congenital anomaly of the kidney and urinary tract (CAKUT) in childhood. The present study identified the possible genetic contributions to primary VUR in children.
methodsPatients with primary VUR were enrolled and analysed based on a national multi-center registration network (Chinese Children Genetic Kidney Disease Database, CCGKDD) that covered 23 different provinces/regions in China from 2014 to 2019. Genetic causes were sought using whole-exome sequencing (WES) or targeted-exome sequencing.
resultsA total of 379 unrelated patients (male: female 219:160) with primary VUR were recruited. Sixty-four (16.9%) children had extrarenal manifestations, and 165 (43.5%) patients showed the coexistence of other CAKUT phenotypes. Eighty-eight patient (23.2%) exhibited impaired renal function at their last visit, and 18 of them (20.5%) developed ESRD at the median age of 7.0 (IQR 0.9-11.4) years. A monogenic cause was identified in 28 patients (7.39%). These genes included PAX2 (n = 4), TNXB (n = 3), GATA3 (n = 3), SLIT2 (n = 3), ROBO2 (n = 2), TBX18 (n = 2), and the other 11 genes (one gene for each patient). There was a significant difference in the rate of gene mutations between patients with or without extrarenal complications (14.1% vs. 6%, P = 0.035). The frequency of genetic abnormality was not statistically significant based on the coexistence of another CAKUT (9.6% vs. 5.6%, P = 0.139, Chi-square test) and the grade of reflux (9.4% vs. 6.7%, P = 0.429). Kaplan-Meier survival curve showed that the presence of genetic mutations did affect renal survival (Log-rank test, P = 0.01). PAX2 mutation carriers (HR 5.1, 95% CI 1.3-20.0; P = 0.02) and TNXB mutation carriers (HR 20.3, 95% CI 2.4-168.7; P = 0.01) were associated with increased risk of progression to ESRD.
conclusionsPAX2, TNXB, GATA3 and SLIT2 were the main underlying monogenic causes and accounted for up to 46.4% of monogenic VUR. Extrarenal complications and renal function were significantly related to the findings of genetic factors in children with primary VUR. Like other types of CAKUT, several genes may be responsible for isolated VUR.
