Phototherapy Induced Hypocalcemia in Term and Preterm Neonates with Hyperbilirubinemia: A Cross-Sectional Study.

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
Introduction: Neonatal jaundice is a common condition affecting 60% of term and 80% of preterm neonates within the first week of life. Phototherapy, though the standard treatment for neonatal hyperbilirubinemia, may cause complications such as hypocalcemia, a significant but lesser-known side effect. This study compared phototherapy-induced hypocalcemia in late preterm and term neonates with unconjugated hyperbilirubinemia, after 48 hours of phototherapy. Methods: This hospital-based descriptive cross-sectional study was conducted in the Neonatal Intensive Care Unit of a tertiary care Hospital from 16th August 2022 to 10th July 2023. A total of 150 neonates, both term and preterm, with hyperbilirubinemia requiring at least 48 hours of phototherapy were enrolled. After ethical approval and informed consent, data were collected using a structured questionnaire and analyzed using IBM SPSS Statistics (version 23.0). Results: After 48 hours of phototherapy, calcium decreased in both groups. In term neonates, it decreased from 9.44±0.59 to 8.57±0.73 mg/dL, mean change was 0.87 mg/dL (95% CI 0.77-0.97) and in preterm neonates from 9.10±0.43 to 7.94±0.79 mg/dL, mean change was 1.16 mg/dL (95% CI 1.01-1.31). The between group difference was 0.29 mg/dL (95% CI 0.11-0.47), Cohen's d = 0.55. Hypocalcemia occurred in 19 (21.30%) term and 21 (34.40%) preterm neonates (RR 1.61, 95% CI 0.95-2.73; RD 13.1%, 95% CI 7.2% to 32.8%). Conclusions: There is a reduction in serum calcium levels in both term and preterm neonates after phototherapy. While exploratory analyses suggested a higher risk of hypocalcemia in preterm neonates, subgroup comparisons were underpowered and should be interpreted cautiously.
