Incidence and predictors of neonatal hyperbilirubinemia requiring phototherapy: A prospective cohort study at a tertiary hospital in Uganda.
Article in PloS one, 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
backgroundNeonatal hyperbilirubinemia remains a leading cause of preventable neurological impairment and death in low-resource settings, particularly in sub-Saharan Africa. Despite its burden, data on incidence and risk factors in Uganda are limited. This study aimed to determine the incidence and predictors of hyperbilirubinemia among neonates at a Ugandan referral hospital.
methodsA prospective cohort study was conducted at Mubende Regional Referral Hospital from November 2024 to February 2025. A total of 539 mother-infant pairs were enrolled, with 534 completing follow-up. Neonates were followed from birth up to 7 days of life. Data on maternal and neonatal characteristics were collected through interviews and medical records. Laboratory tests included total serum bilirubin and ABO/Rh blood grouping. Modified Poisson regression was used to identify independent predictors of hyperbilirubinemia, with statistical significance set at p < 0.05.
resultsThe risk of hyperbilirubinemia requiring phototherapy was increased by close to two times among neonates born to mothers who were underweight, overweight, or obese (based on maternal BMI during pregnancy) (aIRR = 1.703, CI = 1.082-2.680, P = 0.021; aIRR = 1.916, CI = 1.447-3.183, P < 0.001; aIRR = 1.930, CI = 1.233-3.022, P = 0.004), those from households with monthly income <200,000 UGX (aIRR = 1.798, CI = 1.306-2.477, P < 0.001), those delivered by cesarean section (aIRR = 1.835, CI = 1.291-2.610, P = 0.001), and those with premature rupture of membranes (PROM) (aIRR = 1.538, CI = 1.109-2.132, P = 0.010). The risk of hyperbilirubinemia requiring phototherapy was increased by over two times for the preterm (aIR = 2.776, CI = 1.978-3.895, P < 0.001), those in whom feeding was initiated after 1 hour (aIRR = 2.145, CI = 1.411-3.261, P < 0.001), instrumental delivery (aIRR = 2.005, CI = 1.109-3.625, P = 0.021) and ABO incompatibility (aIRR = 2.985, CI = 2.060-4.325, P < 0.001).
conclusion2 in 10 neonates developed hyperbilirubinemia requiring phototherapy. The condition was associated with both modifiable factors, such as delayed initiation of breastfeeding, and non-modifiable factors, including ABO incompatibility, prematurity, and mode of delivery.
