Effect of diet video-drama and telephone messages on improving parental knowledge and diet diversity of malnourished children in Kenya: A randomised controlled trial.
Article in PLOS global public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Severe acute malnutrition (SAM) accounts for 1 million deaths globally each year. Ready-to-use Therapeutic Food (RUTF), recommended for treatment, is often replaced with low-nutrient home foods. We sought to determine the effect of enhanced caregiver counselling, using a dramatized video with contextualized demonstrations of local high-nutrient food (video-drama) and telephone messages on high-nutrient foods (SMS), on children's dietary diversity scores (DDS), weight gain, and caregiver knowledge. This randomised trial enrolled 213 severely malnourished children and caregivers at Mbagathi Hospital in Nairobi. Children were randomised to 3 study arms: standard of care (SOC) (children received RUTF, caregivers received routine nutrition counselling); intervention arm A (caregivers watched the video-drama at enrolment, 1- and 6-weeks post-enrolment plus SOC); and intervention arm B (caregivers received weekly SMS, watched the video-drama plus SOC). Primary outcome was DDS, secondary outcomes were weight gain and caregiver knowledge. Median DDS, mean rate of weight gain and caregiver knowledge were compared between trial arms using Kruskal-Wallis and ANOVA tests, respectively. Children's median age at enrolment was 12 months (IQR 8.0, 16.0), 50.7% were female, 74.6% were breastfeeding and 78.9% were on RUTF. Median caregiver age was 28 years (IQR 24.5, 32.0) and 98% were female. Post-intervention, children in arms A and B had significantly higher median DDS at 5 (IQR 4, 5) versus 4 (IQR 3, 5) in SOC arm (p < 0.001)]. Mean caregiver knowledge was significantly higher in arm A (4.53[±1.17)] and arm B (4.27[±1.04]) compared to 3.77(±0.91) in SOC (p < 0.001). Mean rate of weight gain was similar across study arms [7.60 g/kg/day in intervention arms, 7.30 g/kg/day for SOC (p-value 0.31)]. Video-drama enhanced SOC counselling of local high-nutrient foods, improved children's DDS and caregiver knowledge, but did not improve short-term weight gain. Weekly SMS did not provide additional benefits to the video-drama.
