Predictors of chronic kidney diseases and kidney failure in patients with CAKUT: a cohort study.
Article in International urology and nephrology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
BACKGROUND AND
aimsCongenital anomalies of the kidney and urinary tract (CAKUT) are a group of disorders responsible for the majority of pediatric end-stage renal disease cases. The CAKUT group is phenotypically variable and can affect the kidney alone and/or the lower urinary tract. The aim of the study was to assess the risk factors for the onset of chronic kidney disease (CKD) and the progression to kidney failure (KF, i.e., the need for dialysis or kidney transplantation) in a cohort of patients with CAKUT.
methodWe conducted a longitudinal study at the Nephrology, Dialysis, and Transplantation Unit of Annunziata Hospital of Cosenza. We enrolled consecutive patients with CAKUT from 2005 to 2020. Risk factors for CKD and KF were assessed via Cox regression.
resultsWe studied 87 CAKUT patients (33 females and 54 males). Proteinuria and hypertension were present in 32.2% and 24.1%, respectively, and a high prevalence of urinary tract infections (UTI 56.3%). CAKUT distribution was: 24 bilateral parenchymal abnormalities (BA), 38 renal parenchymal unilateral diseases (PUD), and 25 tubular unilateral diseases (TUD). Proteinuria was more prevalent in BA than in PUD or TUD (54.2% vs 15.8% and 36%, p = 0.006), whereas regular growth was less frequent in BA (33.3% vs 81.6% and 88%, p < 0.001). During a median study follow-up of 205 months, 30 CKD events and 14 KF were registered. BA, anemia, proteinuria, and regular growth independently predicted CKD, while anemia and BA were associated with KF.
conclusionThe long follow-up in these children with CAKUT allowed us to find the predictive risk factors for CKD and progression of KF. Early and appropriate treatment of these risk factors could improve the prognosis of renal disease.
