Incidence of mortality and its predictors among low birth weight neonates in Ethiopia: Systematic review and meta-analysis.
Synthesis 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
backgroundLow birth weight neonates are twentyfold at risk of death. Notably, it is a major public health concern in sub-Saharan Africa, including Ethiopia. Despite the presence of several primary studies on this issue in Ethiopia, the study findings are inconsistent. Hence, this review aimed to assess the pooled incidence and proportion of mortality and predictors among low birth weight neonates.
methodA search of articles from databases (PubMed, CINAHL, Global Index Medicus, and HINAR), and other sources (Google, Google Scholar) were done. All observational studies that assess mortality of low birth weight neonates were included. The Joana Brigs Quality appraisal checklist was used. The pooled incidence rate, proportion, and the effect size of predictors were estimated using a random-effects model. Heterogeneity was assessed using I2 test. Subgroup and sensitivity analysis was conducted. Eggers test and funnel plot were used to assess publication bias. Trim and fill analysis was conducted.
resultFifteen studies with 7539 study participants were included. The pooled incidence rate of mortality was found to be 36.31 (95 CI: 26.37-46.25) per 1000 neonates' day observation and the proportion of mortality was 26.67% (95% CI: 21.83-31.51). Preeclampsia (AHR = 1.38; 95% CI: 1.09-1.75), respiratory distress syndrome (AHR: 1.67; 95% CI:1.25-2.23), perinatal asphyxia (AHR: 1.66; 95% CI: 95%:1.35-2.05), sepsis (AHR: 2.04; 95% CI: 1.59-2.63), not breastfeeding (AHR:5.16; 95% CI: 2.61-9.96), not using KMC (AHR: 4.46, 95% CI: 2.19-9.10), extremely low birth weight (AHR: 3.67; 95% CI: 2.55-5.29), very low birth weight (AHR = 1.75; 95% CI: 1.44-2.12), and prematurity (AHR: 1.55; 95% CI: 1.07-2.24) were predictors.
conclusionBased on the pooled proportion of mortality, above one-fourth of low birth weight neonates died in Ethiopia, and the incidence rate of mortality was significantly high. Preeclampsia, respiratory distress syndrome, perinatal asphyxia, sepsis, not breastfeeding, not using kangaroo mother care, hypothermia, extremely low and very low birth weight, and prematurity were predictors of mortality. Hence, the concerned stakeholder should focus on LBW neonates presented with these predictors. Maternal and neonatal screening, kangaroo mother care, and breastfeeding need to be strictly practiced to reduce mortality. Furthermore, community-based essential newborn care needs to be strengthened. REGISTRATION: CRD42024524189.
