Mortality and risk factors of small vulnerable newborns in 32 low- and middle-income countries.
Article in BMC medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundIn 2022, 2.3 million neonatal deaths occurred globally, the majority of which were in low- and middle-income countries (LMICs). Preterm birth, small for gestational age (SGA), and low birth weight (LBW) are leading causes of neonatal mortality. The Small Vulnerable Newborn (SVN) framework was introduced to unify preterm birth, SGA, and LBW under a single concept. SVNs face significant mortality risks and are predominantly found in LMICs. Understanding the prevalence, mortality risks, and associated factors of SVNs is essential for targeted intervention efforts.
methodsThis study analyzed nationally representative survey data from the Demographic and Health Surveys (DHSs) conducted between 2008 and 2022 in 32 LMICs, covering 197,405 weighted live births among mothers aged 15-49 years. SVN prevalence, neonatal mortality, infant mortality, and associated risk factors were examined using modified Poisson regression and multinomial logistic regression. Population attributable fractions (PAFs) estimated the contribution of modifiable factors.
resultsThe overall SVN prevalence was 23.91% across 32 LMICs. Preterm-SGA showed the highest mortality risks compared to term-nonSGA newborns (neonatal: adjusted RR = 17.51 [95% CI, 12.95-23.67]; infant: adjusted RR = 11.86 [95% CI, 9.20-15.29]). Preterm-nonSGA contributed most to overall mortality (neonatal PAF: 11.72%; infant PAF: 8.15%). Risk patterns varied by subtypes: first parity was primary for preterm-nonSGA (PAF: 14.25%), poverty for term-SGA (PAF: 7.95%), while both insufficient antenatal care (< 4 visits) and first parity were major contributors for preterm-SGA (PAF: 22.68% and 20.41%). Adolescent pregnancy showed the strongest association with overall SVNs (adjusted RR = 1.37 [95% CI, 1.33-1.40]).
conclusionsSVNs remain a significant public health challenge in LMICs, with distinct risk patterns among subtypes suggesting the importance of targeted interventions focusing on antenatal care, socioeconomic factors and adolescent pregnancy prevention.
