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
backgroundUndernutrition among children under five years (CUFY) is a leading global public health issue worldwide, including in Cambodia. This study aimed to determine the prevalence of undernutrition and the mediating effect of maternal depression and household food insecurity on the association between maternal social support and undernutrition among CUFY in Siem Reap Province, Cambodia.
methodA semi-structured questionnaire was utilized to survey 450 mothers in Siem Reap Province, Cambodia. Maternal social support, maternal depression, and household food insecurity were assessed separately using the Maternity Social Support Scale (MSSS), Patient Health Questionnaire-2 (PHQ-2), and Household Food Insecurity Access Scale (HFIAS). Undernutrition indicators were evaluated using height-for-age z-score (HAZ) and weight-for-height z-score (WHZ), calculated according to WHO Anthro standards. A chi-square test was employed to illustrate the distribution of the variables. Structural equation modeling was used to analyze the chain-mediating effect of maternal depression and household food insecurity on the relationship between maternal social support and undernutrition among CUFY.
resultThe prevalence of stunting and wasting among CUFY was 34.9% and 15.6%, respectively. Structural equation modeling (SEM) results showed that maternal social support had a negative effect on children’s undernutrition (β = -0.32), indicating that social support is negatively correlated with child undernutrition. Women with higher levels of social support are less likely to have a child suffering from undernutrition compared to women with lower levels of social support. Household food insecurity and maternal depression mediated the association between social support and undernutrition, and the mediating effect accounted for 29.67% of the total effect.
conclusionUndernutrition among CUFY was relatively high in Siem Reap Province, Cambodia. Maternal depression and household food insecurity partially mediated the association between maternal social support and undernutrition. Providing postpartum workshops promotes awareness about depression, enhances social support, and reduces household food insecurity.
