Effects of unsupervised campus HIIT on fitness and sleep in sedentary male students: a randomized controlled trial.
Trial report in BMC public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07256847 (Effect of 6-Week High Intensity Interval Training on VO2max, Physical Competence and Sleep Quality in Sedentary Male University Students), which is not on this map.

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.

Abstract
backgroundSedentary behavior and poor sleep quality are prevalent among university students and are associated with reduced cardiorespiratory fitness. This randomized controlled trial evaluated the effects of a six-week, campus-based running high-intensity interval training (HIIT) program on physical fitness, sleep quality, and body composition in sedentary male university students.
methodsFifty-six participants (age 21.6 ± 2.4 years) completed the study and were analyzed (HIIT group, n = 28; control group, n = 28). The unsupervised six-week intervention consisted of three weekly sessions of repeated 1-min high-intensity running bouts with recovery periods. Physical fitness, sleep quality, and body composition were assessed. Within- and between-group comparisons were conducted using t-tests, the Wilcoxon signed-rank test, or the Mann–Whitney U test, depending on data normality. Group-by-time interactions were examined using generalized estimating equations.
resultsSignificant group-by-time interactions were observed for VO2max (β = − 6.63, 95% CI − 8.77 to − 4.49, p < 0.001, d = 1.019) and balance (β = − 23.11, 95% CI − 41.16 to − 5.06, p = 0.012, d = 0.544), with the HIIT group showing significant improvements (19.24% and 49.64%, respectively), whereas controls did not. While the group-by-time interaction for sleep quality was not significant, a favorable trend toward within-group improvement was observed in the HIIT group (− 0.57 points, − 12.15%, p = 0.082, d = 0.270), whereas no such trend occurred in the control group (0.07 points, 1.28%, p = 0.892, d = 0.029). No significant changes were observed for the remaining physical fitness indicators or body composition.
conclusionsA six-week, unsupervised campus-based HIIT running program improved cardiorespiratory fitness and balance while showing good adherence and safety in sedentary male university students, confirming its feasibility in a real-world setting. Potential benefits for sleep quality warrant validation in larger randomized trials.
