Hematological parameter changes and associated factors in neonates with hyperbilirubinemia treated with phototherapy.

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
backgroundPhototherapy is a common treatment for neonatal hyperbilirubinemia, however it generates reactive oxygen species and induces apoptosis, potentially influencing blood cells. Assessing changes in hematological parameters is essential to minimize complications and enhance outcomes.
objectiveThis study assessed hematological parameters changes and associated factors in neonates with hyperbilirubinemia undergoing phototherapy.
methodA cross-sectional study was conducted at the University of Gondar Comprehensive Specialized Hospital from May 29 to November 8, 2023. About 246 neonates were selected by convenient sampling. Blood samples were collected before and after phototherapy. Data were entered into Epi-data (4.6.0) and analyzed using SPSS (25.0). The normality of the data was checked by Kolmogorov-Smirnov tests. A paired t-test and Wilcoxon Sign Rank test were used to compare mean differences for normally distributed and skewed data, respectively. Pearson correlation and multiple linear regressions were used to measure the association. A significance level of p < 0.05 was used for statistical significance.
resultAmong neonates, 141 (57.3%) were males, and the median age was 2 days. Phototherapy treatment led to significant increases in WBC and lymphocyte count, 11.02 ± 2.21 to 11.35 ± 2.60, and 3.93 ± 1.19 to 4.16 ± 1.34, respectively. However, hemoglobin and platelet count significantly decreased from 15.05 ± 3.67 to 14.55 ± 2.62, and 243.23 ± 74.78 to 239.32 ± 73.29, respectively. Other blood cell parameters were unaffected. WBC and lymphocytes showed a positive association with preterm neonates and intensive phototherapy, while WBC count showed a negative association with total bilirubin. Hemoglobin counts are positively associated with total bilirubin but negatively associated with neonate age and treatment duration. Platelet count showed negative associations with low-birth-weight neonates, intensive phototherapy, and treatment duration. After treatment, normocytic normochromic cells increased, microcytic hypochromic decreased, and abnormal RBC shapes were reduced.
conclusionPhototherapy significantly affected key hematological parameters, notably WBC, lymphocytes, hemoglobin, and platelet count. Treating neonates with intensive phototherapy affects WBC and platelet counts while undergoing phototherapy for a longer duration affects hemoglobin and platelet counts. Therefore, routine monitoring of these parameters is crucial for neonates undergoing intensive or prolonged phototherapy.
