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
Introduction: Undernutrition remains a significant public health challenge in the Democratic Republic of Congo (DRC). This study aims to identify dietary and non-dietary factors associated with undernutrition among children aged 6-23 months using the Composite Index of Anthropometric Failure. Methodology: The secondary analysis was conducted using data from the 2023 National Nutrition Survey, a nationally representative cross-sectional study. The final analytical sample consisted of 5396 children, stratified into two age bands 6-11 months (n=1792) and 12-23 months (n=3604). Bivariate analysis (p<0.2), Multivariable logistic and stepwise regression models (p<0.05) were used to identify factors associated with undernutrition. Results: The overall prevalence of undernutrition was 47.4%, rising significantly from 37.4% in infants aged 6-11 months to 52.6% in children aged 12-23 months. Stepwise logistic regression identified distinct risk profiles: for the 6-11 month group, male sex (adjusted OR (aOR)=1.7; 95% CI 1.3 to 2.1) and larger households with >2 children (aOR=1.3; 95% CI 1.1 to 1.6) increased the undernutrition, while acceptable minimum meal frequency (MMF) was the primary protective factor (aOR=0.12; 95% CI 0.08 to 0.19). Among the 12-23 month, high dietary diversity (aOR=0.5; 95% CI 0.4 to 0.7), acceptable MMF (aOR=0.6; 95% CI 0.5 to 0.8) and maternal education significantly reduced undernutrition. Conversely, rural residency, recent diarrhoea (aOR=1.4; 95% CI 1.2 to 1.7) and poor hand hygiene remained major factors associated with undernutrition. Conclusion: Traditional indices significantly underestimate the true nutritional burden in the DRC. These findings underscore the need for a National Nutrition Programme to implement multisectoral interventions that prioritise maternal literacy and the integration of Water, Sanitation and Hygiene protocols to address the diverse drivers of undernutrition.
