Effect of health educational intervention on early detection of sickle cell disease among adolescent population in tribal areas of East Singhbhum district, Jharkhand: A study protocol.

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
Sickle Cell Disease (SCD) remains a public health challenge in India, particularly among tribal populations. Gaps persist in early detection, awareness, and culturally appropriate interventions, especially among adolescents, a key target group for long-term prevention. The study aims to evaluate the effect of a school-based educational intervention on the awareness, attitude, and early detection of SCD among adolescents in tribal and non-tribal areas of East Singhbhum district, Jharkhand. A sequential explanatory mixed-methods design will be used. In the quantitative phase, adolescents aged 13-19 years from selected government schools will undergo baseline and follow-up assessments of knowledge and attitudes using structured questionnaires. A health education session will be delivered, followed by screening for anemia and SCD using hemoglobin estimation and the solubility test. In the qualitative phase, in-depth interviews with stakeholders, including healthcare providers, ASHAs, school staff, caregivers, and affected adolescents, will explore perceptions, barriers, and feedback related to the SCD and National Sickle Cell Anemia Elimination Mission, 2023 implementation. A quasi-experimental one-group pretest-posttest was conducted among 41 adolescents (13-15 years) from a government school. Knowledge scores increased from 5.31 ± 2.87 to 12.57 ± 2.09 (mean difference: 7.26, 95% CI: 6.10-8.42, p < 0.001). Attitude scores from 1.44 ± 9.21 to 55.83 ± 8.42 (mean difference: 54.39, 95% CI: 50.89-57.89, p < 0.001). Willingness to undergo SCD testing rose from 37% to 83% post-intervention. Stakeholder feedback indicated high acceptability and enthusiasm for similar sessions. The study will provide critical insights into the effectiveness of adolescent-focused health education in enhancing SCD awareness and screening uptake. It will also highlight disparities between tribal and non- tribal populations and inform policy-level recommendations for targeted, equitable interventions. This research will address gaps in adolescents' SCD awareness and early detection, contributing to the national goal of SCD elimination through evidence-based, community-embedded strategies.
