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
This study investigated perceived exertion (RPE) differences among soccer players at two competitive levels - Tier 2 (trained) and Tier 3 (highly trained) - during small-sided games (SSGs) and high-intensity interval training (HIIT), while controlling for internal physiological load using percentage of heart rate reserve (%HRreserve). Seventy-seven male university players from the China University Football Association participated (Tier 2: n = 37; Tier 3: n = 40). Each player underwent a fitness assessment to determine HRmax and HRrest, followed by four randomized training sessions: 5v5 SSGs, 1v1 SSGs, long HIIT, and short HIIT. Heart rate was continuously monitored, and players reported RPE using the Borg CR10 scale immediately post-session. A linear mixed-effects model was used, with competitive level and training format as fixed effects, and %HRreserve included as a statistical covariate. The analysis revealed a significant interaction between training format and competitive level (F(3, 224.761) = 3.20, p = .024), indicating that the influence of training format on RPE varied by competitive level. A significant main effect of training format was also found (F(3, 234.484) = 11.24, p < .001). Specifically, Tier 3 players reported higher RPE during short HIIT than Tier 2 players (p = .002). Both groups reported lower RPE during 5v5 SSGs compared to 1v1 SSGs and HIIT formats (all p ≤ .003). These findings show that training format influences RPE in a format- and tier-specific manner, even when accounting for internal physiological load. For coaches and sports scientists, larger-sided SSGs may be useful to reduce perceived exertion while maintaining cardiovascular demand. Future research should include elite players and assess psychological and physiological mediators to better understand the complex drivers of perceived effort.
