The Influence of Gender on Isokinetic Knee Performance.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionGender-related differences in muscle performance are well documented and are influenced by muscle mass, neuromuscular activity, and hormonal factors. This study aimed to evaluate the influence of gender on isokinetic knee performance and body composition.
methodsThis was a cross-sectional, observational, comparative study involving 30 healthy adults (15 men, 15 women), conducted in Marrakech. Body composition was assessed using multifrequency bioelectrical impedance analysis. Muscle performance was evaluated using an isokinetic dynamometer at various angular velocities and contraction modes (concentric, eccentric).
resultsMen showed higher muscle mass (54.79 ± 2.43 kg vs. 41.14 ± 6.18 kg) and lower fat mass (13.15 ± 3.65 kg vs. 20.61 ± 7.12 kg) than women. Peak torque values were consistently higher in men across all velocities and contraction modes, with statistically significant differences in most testing modalities (all p < 0.001), except for eccentric right extensors at 30°/s (p = 0.065). The hamstring-to-quadriceps (H/Q) ratio did not differ significantly between sexes at 60°/s or 180°/s but was lower in women at 240°/s on the right side (p = 0.028). Muscle mass was strongly correlated with performance (r = 0.522 to 0.877), while fat mass showed weaker negative correlations with peak torque (r = -0.267 to -0.420). Conclusion: Gender has a significant influence on isokinetic performance. The lower H/Q ratio observed in women may have implications for neuromuscular balance and injury prevention. Gender-specific rehabilitation programs are recommended.
