Impact of transcatheter PDA closure on renal function in extremely low birth weight infants-a multicenter study.
Article in Journal of perinatology : official journal of the California Perinatal Association, 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
objectivesTo describe the impact of transcatheter PDA closure on renal function in these premature infants with and without pre-existing renal insufficiency. STUDY
designThis retrospective study was conducted by 4 U.S. pediatric centers and included 245 eligible patients who underwent successful transcatheter PDA device closure. Renal insufficiency in these patients was noted along with risk factors. Renal function over multiple time periods was assessed out to 2 months post intervention.
resultsIn total, 245 eligible patients underwent successful transcatheter PDA device closure. In the first 24 h post device closure, the urine output increased from 3.7 to 4.1 ml/kg/h (p < 0.001) with a decrease in serum creatinine (0.40 to 0.37 mg/dL, p < 0.001) and blood urea nitrogen (16 to 12 mg/dL, p < 0.001). This trend of improved renal function continued through 2 months post-device closure. A total of 59 patients (32%) met the definition for acute renal insufficiency prior to cardiac catheterization. The serum creatinine and BUN had a significantly greater decline from baseline for the AKI cohort in comparison to all others at both 1 week post procedure (-0.21 ± 0.04 vs -0.04 ± 0.03, P < 0.0001 and -8.4 ± 1.8 vs -2.4 ± 1.4, P < 0.001) and 1 month post procedure (-0.39 ± 0.04 vs -0.07 ± 0.03, P < 0.0001 and -12.0 ± 1.8 vs -2.3 ± 1.5, P < 0.0001).
conclusionAll patients showed a positive trend in renal function post PDA device closure with a significant increase in urine output in the first 24 h post closure. Patients with acute renal insufficiency experienced notable improvement in renal function post PDA device closure, even with the use of contrast.
