Concomitant Bladder Neck Incision in Patients with Posterior Urethral Valve and Blad-der Neck Hypertrophy: Short-term Outcomes of a Randomized Controlled Trial.

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
introductionConcomitant bladder neck incision (BNI) with posterior urethral valve ablation (VA) was proposed to mitigate the long-term sequela of posterior urethral valve (PUV) and reduce the reoperation rates. This study aimed to investigate the short-term outcomes of concomitant BNI and VA, particularly short-term reoperation rates. PATIENTS AND
methodsPatients with PUV and bladder neck hypertrophy on preoperative imaging were randomized to undergo VA only or VA with concomitant BNI. Surgical reoperation within one year was the primary endpoint. Renal function, UTI, hydronephrosis and VUR improvement at one year were secondary endpoints.
resultsSixty-three patients were included in the final analysis, 33 in VA group (group A) and 30 in concomitant BNI and VA group (group B). After one year of follow-up, the reoperation rate was similar [5(15.2%) in group A and 3(10%) in group B, p=0.18]. The median (IQR) nadir serum creatinine was lower in group B [0.2 (0.1-0.3) vs. 0.2 (0.2-0.4) mg/dL in group A, p=0.049]. The last follow-up serum creatinine median (IQR) eGFR [107 (89.5-163) in group A vs. 139(102-165) mL/min/1.73 m2 in groups B, p=0.37], and febrile UTI rates were not different between the two groups. Hydronephrosis improved/ resolved in 27 (40.9%) renal units in group A vs. 33 (55%) renal units in group B (p=0.286). Vesicoureteral reflux improved/ resolved in 23(34.8%) and 12 (20%) renal units in group A and B, respectively (p=0.074).
conclusionConcomitant BNI with VA does not confer a lower short-term reoperation rate or better upper urinary tract outcomes compared to VA only.
