Effectiveness of Genetic Counseling Modalities on Knowledge, Attitudes, and Premarital Screening Intentions for Thalassemia Prevention: A Multi-Site Three-Arm Randomized Controlled Trial.
Trial report in International journal of environmental research and public health, 2026. 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
Thalassemia prevention relies on effective premarital screening. However, participation remains suboptimal because of multiple individual, sociocultural, and structural barriers, including limited knowledge, stigma, cultural and religious beliefs, healthcare accessibility, and socioeconomic constraints. This multi-site three-arm randomized controlled trial evaluated the effectiveness of digital leaflet-based, educational video-based, and face-to-face genetic counseling on knowledge, attitudes, and screening intentions among prospective couples in Ciamis District, Indonesia. A total of 177 prospective couples were randomized (digital leaflet = 59, video = 59, face-to-face = 59). After follow-up, 41, 53, and 59 participants, respectively, completed the post-intervention assessment and were included in the final analysis. Outcomes were measured at baseline and post-intervention using validated questionnaires and analyzed using Wilcoxon signed-rank tests and repeated-measures analysis of variance. Digital leaflet-based counseling significantly improved knowledge and screening intention (
