Population attributable fraction of risk factors for anemia among children aged 6-59 months: A multilevel complex data analysis using modified poisson regression model in Sub-Saharan Africa.

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
backgroundAnemia among children under five remains a significant public health concern in sub-Saharan Africa (SSA). While numerous studies have examined its associated factors, limited evidence exists on the public health impact of modifiable risk factors. This study assessed the population-attributable fraction (PAF) of risk factors for anemia among children aged 6-59 months across 27 SSA countries.
methodsA secondary data analysis was conducted using Demographic and Health Survey (DHS) data from 27 SSA countries, including a weighted sample of 124,285 children. Data management and analysis were done using STATA-14 software. The presence of clustering was assessed using the Intra-cluster Correlation Coefficient (ICC), Median Odds Ratio (MOR), and Likelihood Ratio Test (LRT). A multilevel modified Poisson regression model was employed to estimate adjusted Prevalence Odds Ratios (aPOR) and the corresponding PAF with 95% Confidence Intervals (CI), and the Population Attributable Fraction (PAF) with the 95% CI was estimated using the aPOR and the prevalence of exposure.
resultsThe overall prevalence of anemia among children in SSA was 61.99% (95% CI: 61.73, 62.27). Significant risk factors included maternal anemia (PAF = 7.37%), low maternal education (PAF = 5.86% for no formal education), poor household wealth status (PAF = 3.52% for the poorest), lack of media exposure (PAF = 0.76%), child undernutrition (stunting PAF = 1.31%, underweight PAF = 0.84%), diarrheal (PAF = 1.19%) and febrile illness (PAF = 2.26%), and unimproved toilet facilities (PAF = 1.02%).
conclusionMaternal anemia, low maternal educational status, poverty, poor sanitation, inadequate media access, unimproved toilet facilities, and childhood illness significantly contribute to anemia in SSA. Targeted interventions to improve maternal and child health, enhance education, and ensure better nutrition and sanitation could help reduce childhood anemia in the region.
