Epidemiology and related risk factors of prolonged QT interval in neonates.

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
Objective: To investigate the epidemiology and related risk factors of prolonged QT interval (PQTI) in neonates. Methodology: This was a retrospective study. A cohort of one thousand neonates admitted to the Obstetrics and Neonatology department of The People's Hospital of Suzhou New District from January 2021 to December 2023 was enrolled in the study. Neonates were categorized into four groups based on their birth gestational age: healthy full-term group, diseased full-term group, healthy preterm group, and diseased preterm group. The incidence of PQTI in neonates across these group was observed, compared and investigated the risk factors for PQTI. The diagnostic value of QTcHod, QTcFri, and QTcFra was assessed using Receiver Operating Characteristic (ROC) curve analysis. Results: Among the 1,000 neonates, 51(5.10%) exhibited PQTI. The incidence of PQTI was 0.98% (7/714) for Group-1, 3.64%(2/55) for Group-2, 15.05%(28/186) for Group-3, and 31.11%(14/45) for Group-4. Statistically significant differences were observed in the incidence of PQTI between the four groups(χ² = 137.637, Conclusion: PQTI is relatively uncommon in neonates. Birth gestational age, 1-minute Apgar score, 5-minute Apgar score, PROM, fetal distress, QTcHod, QTcFri, and QTcFra are significant risk factors for PQTI in neonates.
