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
Background: Prematurity remains the leading contributor for neonatal death globally, with Ethiopia having the 4th highest incidence of neonatal deaths. Clarifying specific contributors of prematurity-related neonatal death is critical to improve outcomes. Objective: We evaluated neonatal causes of death among premature neonates at St. Paul's Hospital Millennium Medical College's (SPHMMC) neonatal intensive care unit (NICU). Study design: Through a retrospective electronic database, we evaluated mortality outcomes for neonates <37 weeks' gestation admitted to SPHMMC NICU from February 2022-May 2023, excluding those with congenital anomalies. Logistic regression models assessed the association between variables and outcomes. Results: Of 1033 premature neonates included in the analysis, 228 (22.1 %) died. Mortality was inversely related to birthweight with extremely low birthweight neonates (≤1000g) having 84 % mortality. The top 3 causes of prematurity-related mortality included respiratory distress syndrome (67.7 %, 159/228), sepsis (39.5 %, 90/228), and pulmonary hemorrhage (25.0 %, 57/228). Neonates that died from pulmonary hemorrhage had higher antenatal corticosteroids (ACS) exposure (66.7 % vs 36.7 %, p < 0.001), less chorioamnionitis (29.5 % vs 55.5 %, p = 0.004), and higher cesarean section delivery (71.9 % vs 53.1 %, p = 0.02). Notably, there were no associations between mortality and ACS exposure or lack thereof in the overall cohort in multivariate models. Conclusion: While respiratory distress syndrome and sepsis are commonly reported findings of premature mortality, surprisingly, 25 % of premature newborns died from pulmonary hemorrhage at SPHMMC NICU. Further investigations are needed to clarify the causes and contributing factors leading to premature death and to determine whether pulmonary hemorrhage is an underreported, underrecognized contributor to prematurity-related mortality globally.
