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: eHealth literacy (eHL) has emerged as an important competency for promoting health equity. Vocational college students are often considered a digitally vulnerable population. Understanding the heterogeneity of eHL in this population and the underlying psychological mechanisms is essential for designing effective health promotion interventions. Objective: This study aimed to identify latent profiles of eHL among vocational college students, compare differences in health-promoting lifestyle levels across profiles, and examine the mediating role of health self-efficacy. Methods: A cross-sectional survey was conducted among vocational college students from February to March 2026. The eHealth Literacy Scale, the Health Self-Efficacy Scale, and the Health-Promoting Lifestyle Profile-II were used to collect data. Latent profile analysis (LPA) was used to identify sub-groups, and bias-corrected bootstrap analyses were performed to test the mediation effects. Results: A total of 594 vocational college students were included. The mean total eHL score was 25.21 ± 5.26. Three distinct profiles were identified: Low Application-High Confidence (Profile 1, 15%), High Application-Low Critical Thinking (Profile 2, 52%), and High eHealth Literacy (Profile 3, 33%). For health-promoting lifestyle, students in Profiles 2 and 3 scored significantly higher than those in Profile 1 (both Conclusion: eHL among vocational college students was heterogeneous, and health self-efficacy was statistically tested as a significant mediator in the association between eHL profiles and health-promoting lifestyle, though causal inference is limited by the cross-sectional design. These findings suggest that vocational college students should not be treated as a homogeneous population in health promotion practice. Instead, person-centered interventions should be tailored to specific eHL profiles.
