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.

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: Despite progress in reducing stunting and underweight among children in Pakistan, significant disparities remain between poor and non-poor households. Specifically, socio-economic inequalities, limited access to healthcare, and inadequate maternal and child nutrition primarily drive these disparities. Analyzing differences in child nutritional outcomes is crucial for understanding the underlying factors contributing to health inequalities, particularly across socio-economic strata. Nevertheless, there is not enough of empirical research that specifically investigates the determinants of these disparities in Pakistan by deconstructing child nutritional inequality in the country. This study aims to address this gap by identifying the key factors contributing to unequal child nutrition outcomes. Methodology: This study examines data from the Pakistan Demographic and Health Surveys (PDHS) of 2013 and 2018, including 3,051 children from the 2013 PDHS and 4,013 from the 2018 PDHS. Height-for-age Results: Children from non-poor households showed significantly higher HAZ scores by 0.75 standard deviations (SDs) and WAZ scores by 0.50 SDs compared to those from poor households. Major socioeconomic factors, including maternal education, access to healthcare, sanitation, and water facilities, mainly explain this difference. Blinder-Oaxaca decomposition analysis further clarified these inequalities, indicating that 62% of the HAZ gap and 54% of the WAZ gap stem from endowment effects. The prevalence of endowment effects indicates that structural inequities, rather than behavioral differences, are the principal obstacles to attaining SDG 2.2. Discussion: This study highlights the importance of equity-focused policies to reduce child undernutrition in Pakistan by targeting key determinants such as maternal education, healthcare access, and systemic inequalities. Findings link better nutrition to improved cognitive and mental health outcomes, supporting inclusive social policies and SDG targets. Structural factors, rather than individual behaviors, primarily drive observed disparities and intergenerational health issues. Future research should explore targeted interventions addressing maternal education and service delivery inequities to achieve sustainable reductions in child undernutrition.
