Tracking key metrics: fluctuations in external and internal load across game quarters in collegiate basketball players.
Article in BMC sports science, medicine & rehabilitation, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundThis study aimed to explore the quarter-by-quarter variations in external and internal load and their interrelationships throughout basketball games among collegiate basketball players.
methodsThis longitudinal observational study analyzed data from 18 official games, yielding a total of 470 data points (quarter 1 (Q1): 112, Q2: 128, Q3: 122, Q4: 108) from 14 male players of the Chinese University Basketball Association. Only players without injury records who completed at least 15 min per game and 5 min per quarter in at least five games were included in the final analyses. Catapult S7 devices and Ratings of Perceived Exertion (RPE) were employed to assess both external and internal load variables. Linear mixed-effects models and repeated-measures correlations were utilized to assess differences in external and internal load between backcourt and frontcourt players, as well as to examine the relationship between RPE and objective load metrics across game quarters. Decision tree visualizations were employed to analyze load thresholds and identify key quarter-specific features that differentiate player performance.
resultsBackcourt players exhibited higher RPE (Q1: p < 0.01, ES = 0.72; Q2: p < 0.001, ES = 1.3), PlayerLoad (PL)·min
conclusionThis study highlights position-specific physical demands across game quarters in basketball, with backcourt players showing higher intensity (RPE, PL·min
