Exploring Behavioral Interventions to Enhance Adherence to Multiple Micronutrient Supplementation Among Pregnant Women in Cambodia: A Mixed-Methods Study.

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
BACKGROUND/
objectivesMultiple micronutrient supplements (MMS) are more effective in improving maternal and birth outcomes compared to iron and folic acid (IFA) supplementation during pregnancy. High adherence to MMS is critical to achieving all the anticipated health benefits. Therefore, to ensure successful program implementation of transitioning to MMS in Cambodia, implementation research has been prioritized. The objective of this study was to assess the relevance, acceptability, utility and short-term, exploratory adherence outcomes of three behavioral interventions designed to support adherence to daily MMS intake and to promote healthy pregnancy practices.
methodsThis mixed-methods study, conducted in four provinces in Cambodia, involved 12 focus group discussions (FGD) with 36 pregnant women who were exposed to three distinct behavioral interventions (family support, a tracking calendar, and educational videos). FGDs were held after three weeks of exposure to each intervention. Data was analyzed using a COM-B model, with inductive codes added to capture emerging themes.
resultsFamily support emerged as the most preferred and perceived as the most effective intervention, with participants consistently valuing the presence, encouragement, and practical assistance offered by husbands and other close family members. The second most preferred were educational videos, which were perceived to effectively convey key messages in an engaging, relatable way, overcoming literacy barriers. Finally, the calendar supported habit formation and appealed to first-time mothers but posed challenges for low-literacy users. Across interventions, findings reflect participants' perceived effectiveness and preferences rather than comparative efficacy.
conclusionsThis study provided insights into Cambodian women's preferences and experiences with three distinct interventions designed to improve adherence over a short-term, 3-week exposure period per intervention. An integrated, multilevel approach that combines family-focused, educational, and system-level strategies is recommended for further piloting and scale-up, with longer-term studies needed to assess comparative efficacy for adherence and health outcomes.
