Developing and evaluating a localized health education curriculum in Qinghai, China: a cluster randomized experimental study in high schools.

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: This study aimed to develop and preliminarily evaluate a localized health education curriculum tailored to the cultural, environmental, and health needs of high school students in Qinghai Province, China. Methods: A pretest-posttest pilot cluster-randomized design was employed involving 180 Grade 11 students from four intact classes. Within both the ethnic minority and general education categories, one class was randomly assigned to the experimental group and the other to the control group. The primary outcome was the post-test overall mean health literacy score adjusted for the corresponding pre-test score. A fixed-effects model including intervention group, class type, and their interaction was used. A linear mixed model with a random intercept for class was additionally conducted as a sensitivity analysis. Results: The adjusted mean scores were 3.774 for the experimental group and 3.514 for the control group, yielding an adjusted mean difference of 0.259 [ Conclusion: The findings provide preliminary evidence that a localized health education curriculum may improve health literacy among high school students in Qinghai Province. However, because only four clusters were included, class-level variance could not be estimated reliably and cluster-level confounding cannot be ruled out. The findings should therefore be interpreted as preliminary rather than definitive evidence of curriculum effectiveness.
