Effect of nutrition behavior change communication on nutrition knowledge and dietary practices of pregnant adolescents in West Arsi, Central Ethiopia: a cluster randomized controlled trial.

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
Objective: This study investigated the effect of communication about nutritional behavior changes on the nutritional knowledge and dietary practices of pregnant adolescents in the West Arsi Zone, Central Ethiopia. Methods: A two-arm parallel cluster randomized controlled trial was conducted in West Arsi, Central Ethiopia, to assess a Nutritional Behavioral Change Communication (NBCC) intervention based on the Health Belief Model (HBM). Implemented by the Alliance for Development (AFD) from 16 weeks of gestation, the intervention included food preparation demonstrations and NBCC sessions for pregnant adolescents and their husbands. The study involved 207 and 219 pregnant adolescents in 14 interventions and 14 control clusters, respectively. The primary outcome was dietary practice, and the secondary outcome was nutritional knowledge. Conducted from October 15, 2022, to July 15, 2023, the intervention group attended four counseling sessions, while the control group received standard nutritional counseling. Generalized estimating equations and the difference-in-differences method were used to estimate the net treatment effect. Results: The mean age of the study participants was 17.8 ± 1.2 years, ranging from 15 to 19 years. The appropriate dietary practice rate increased by 20.3 percentage points in the intervention group and decreased by 5.6 percentage points in the control group. After controlling for possible confounders, the odds of appropriate dietary practices increased by 13% in the comparison group [AOR = 1.13; 95% CI = 1.02, 1.2], and pregnant adolescents in the intervention group had an AOR which was 3.7 times that of the comparison group in appropriate dietary practices [AOR =4.2, 95% CI = 2.6, 5.3]. The odds of good nutritional knowledge increased in both groups, however, the NBCC group had an increase 5.5 times (95%CI: 3.8, 8.1) that of the comparison group. Conclusion: NBCC through AFDs based on the HBM is an effective approach for increasing the proportion of pregnant adolescents who practice appropriately and have good nutritional knowledge.
