Normative Hamstrings and Quadriceps Isometric Strength Values and Hamstrings-Quadriceps Asymmetry in Healthy Collegiate Soccer and Basketball Players.
Article in International journal of exercise science, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
The objectives of this study were to report weight-normalized, sex- and sport-stratified normative values for hamstrings and quadriceps isometric strength in collegiate soccer and basketball players using a low-cost hand-held dynamometer and assess the prevalence of "substantial" hamstrings-quadriceps (H/Q) ratio strength imbalance (<0.6) among players. Ninety-four healthy collegiate male and female soccer and basketball players (age range: 18-24 years) were examined for baseline isometric hamstrings and quadriceps strength using a handheld isometric dynamometer with standardized and valid protocols. For soccer, the mean (95%CI) weight-normalized peak isometric strength values (considering dominant limbs) were 3.29 (2.90 to 3.64) N/kg (hamstrings) and 5.48 (4.96 to 6.00) N/kg (quadriceps) in male players and 2.62 (2.39 to 2.85) N/kg (hamstrings) and 4.55 (4.14 to 4.96) N/kg (quadriceps) in female players. For basketball, the mean (95% CI) peak strength values were 2.97 (2.72 to 3.21) N/kg (hamstrings) and 4.89 (4.44 to 5.33) N/kg (quadriceps) in male players and 2.48 (2.15 to 2.80) N/kg (hamstrings) and 4.21 (3.54 to 4.87) N/kg (quadriceps) in female players. The prevalence of substantial H/Q strength imbalance was 37% (95%CI: 24% to 52%) in soccer and 44% (95%CI: 29% to 60%) in basketball players. This study is first to provide normative values for peak isometric hamstrings and quadriceps strength using a low-cost hand-held dynamometer. The normative database from this study is valuable to coaches, sports medicine professionals, exercise scientists and other stakeholders to inform injury prevention, rehabilitation progression, return to play decisions and performance goals in collegiate soccer and basketball players.
