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
backgroundSocioeconomic inequality remains a critical determinant of health outcomes worldwide, particularly in low- and middle-income countries. In Kenya, one of the most pressing maternal and child health challenges is the high prevalence of low birth weight (LBW), which is a key indicator of infant health and a strong predictor of neonatal and child morbidity and mortality. Therefore, exploring socioeconomic inequality and the determinants of LBW in Kenya is essential for developing effective policies and interventions.
methodsA cross-sectional study was conducted using secondary data from the 2022 Kenyan Demographic and Health Survey. A weighted total sample of 4717 live births in the two years prior to the survey was included in the study. The concentration index and concentration curve were used to investigate socioeconomic inequality in LBW among newborns. In addition, a multilevel regression model was used to identify the determinants, and the adjusted odds ratio with a 95% confidence interval was used to determine statistical significance.
resultsThe prevalence of low birth weight among live births in Kenya was 8.71%. It was inequitably distributed across socioeconomic groups, with a concentration index of (-0.0295), with a higher concentration of LBW infants among mothers living in the lowest socioeconomic quintile. Mothers without formal education, poor wealth index, female sex, multiple births, and antenatal care visits were all significant predictors of LBW.
conclusionThis study highlights that LBW remains a significant issue in Kenya, disproportionately concentrated in households in the lowest socioeconomic quintile. Factors such as lack of maternal education, poverty, being female, being a twin, and inadequate antenatal care visits were significant predictors. To address these issues, it is important to improve maternal education, economic prosperity, healthcare accessibility, gender-sensitive approaches, and specialized care for multiple pregnancies, and encourage regular antenatal care visits for better birth outcomes and to reduce LBW prevalence. Hence, Kenyan governments and non-governmental organizations should address the complex factors to improve birth outcomes and reduce LBW.
