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: Common mental disorders (CMDs) are increasingly recognized as a major public health challenge worldwide, with adolescent girls bearing a disproportionate burden. Moreover, iron deficiency (ID) and iron deficiency anemia (IDA) remain prevalent nutritional problems among adolescents. Observational studies have highlighted that the prevalence of CMD is higher among anemic individuals compared to their non-anemic counterparts. This study hypothesizes that preventing anemia through weekly iron and folic acid supplementation (WIFAS) among adolescent girls may have a positive effect on CMDs. However, the potential effect of WIFAS on CMDs remains unexplored. This critical evidence gap highlights the need for targeted research. Therefore, this study aimed to assess the effect of WIFAS on CMD among adolescent girls in the Central Ethiopia Region. Method: This study employed a school-based, parallel-cluster randomized controlled trial (RCT) design, involving 306 adolescent girls across 12 clusters in the Silti and Kibet Districts of the Central Ethiopia Region. Participants were proportionally allocated, with 153 girls assigned to the intervention group (six clusters in Silti District) and 153 to the control group (six clusters in Kibet District). The outcome variable, CMD score, was treated as a continuous measure and assessed using the World Health Organization's (WHO) Self-Reporting Questionnaire (SRQ-20). Data were collected at baseline and endline, with the latter conducted 6 months after the completion of the WIFAS. Linear mixed-effects models (LMEMs) were used to examine the association between WIFAS and CMD. Result: The findings of this study indicated that adolescents who received WIFAS had significantly lower CMD scores compared to those who did not ( Conclusion: The findings of this study revealed that WIFAS significantly reduced CMD scores among adolescent girls. This suggests that WIFAS may offer mental health benefits in addition to its known role in preventing anemia and ID. Hence, integrating WIFAS into school-based health programs should be prioritized as a potential strategy to improve mental health outcomes among adolescent girls.
