Trends in procedural closure of patent ductus arteriosus among children from 2011 to 2022 in Japan.
Article in Pediatrics international : official journal of the Japan Pediatric Society. 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
backgroundAlthough surgery was traditionally the primary modality for definitive patent ductus arteriosus (PDA) closure, the indications for transcatheter closure have expanded with device advancements in recent decades. This study aimed to describe the trends in surgical and transcatheter closure for PDA in Japan.
methodsPatients aged <16 years who underwent procedural PDA closure between April 2011 and March 2023 were identified from the Diagnosis Procedure Combination database in Japan. Considering the redaction of the requirements for the Amplatzer Duct Occluder (age ≥6 months and weight ≥6 kg) in 2016, patients were stratified by this erstwhile weight threshold (6 kg) to evaluate the impact of this regulatory change. We analyzed data from consecutive 2-year periods. We examined the trend in the proportion of transcatheter closure among all procedural PDA closures using multivariable mixed-effects logistic regression models.
resultsThe study enrolled 5638 patients (3235 weighing <6 kg and 2403 weighing ≥6 kg). The proportion of transcatheter closure increased over time from 13/466 (2.8%) patients in 2011-2012 to 60/431 (13.9%) in 2021-2022 in patients weighing <6 kg (adjusted odds ratio 1.46, 95% confidence interval 1.29-1.67), and from 268/316 (84.8%; 2011-2012) to 392/416 (94.2%; 2021-2022) in patients weighing ≥6 kg (1.56, 1.38-1.76).
conclusionsAlthough the proportion of transcatheter closure steadily increased in patients weighing <6 kg, its implementation was slow and surgical closure remained the primary treatment. Transcatheter closure has become the predominant option for patients weighing ≥6 kg.
