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
introductionMulticystic dysplastic kidney disease (MCDK) is a notable congenital anomaly of the kidney and urinary tract, with potential risk for chronic kidney disease, yet data from sub-Saharan Africa remain scarce. This study examined the pattern of MCDK, associated contralateral kidney abnormalities, determined the predictors of MCDK involution and assessed short-term outcomes in children followed beyond one year in South Africa.
methodThis retrospective study involved children under 13 years of age with suspected unilateral MCDK, confirmed on kidney ultrasound and [
resultsAmong 1,581 new cases, 98 (6.2%) had unilateral MCDK. 50% were male, and 57.1% had left-sided involvement. Median follow-up was 60 months (IQR: 12-72). Contralateral kidney abnormalities occurred in 17 (17.3%), most commonly duplex kidney (35.3%) and ureteropelvic junction obstruction (29.4%), but no vesicoureteric reflux was noted. Of 81 children followed beyond a year, 80.2% demonstrated contralateral hypertrophy, and 69.1% exhibited involution of the affected kidney. Initial kidney size ≤ 5.0 cm was the sole predictor of involution (Hazard Ratio: 2.42, 95% CI: 1.31-4.48). Urinary tract infections occurred in 18.5%, proteinuria in 2.5%, hypertension in 1.2%, and 2.5% developed chronic kidney disease related to contralateral dysplasia. One nephrectomy was performed, and no malignancies or deaths. At last follow-up, 28.4% were lost to follow-up, and 12.3% had transitioned to adolescent clinics.
conclusionAll MCDK cases were unilateral, with duplex kidney being the most common contralateral abnormality, a distinctive finding previously unreported. Follow-up into adolescence may be beneficial, as progression of chronic kidney disease is rare in those without contralateral anomalies. Multicentre long-term studies are needed to provide standardised follow-up guidelines.
