Does knee joint proprioception differ according to age and gender in healthy adults?

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 investigate the effects of age and gender on knee joint position sense (KJPS) and movement sense (KJMS) in healthy adults.
methodsGeneral physical activity was evaluated using the International Physical Activity Questionnaire-Short Form (IPAQ-Sf) and the Tegner Activity Scale (TAS). Knee discomfort was measured with the Lysholm Knee Score (LKS), and knee-related symptoms and functional status were assessed using the Knee Osteoarthritis Outcome Score (KOOS). Knee joint position sense (KJPS) was tested at 15°, 30°, 45°, and 60°, while knee joint movement sense (KJMS) was evaluated at 60° and 90°. Participants were categorized by gender (male, female) and age (18-29, 30-44, ≥ 45 years). Mixed-effects models were applied to analyze numerical data, and post hoc comparisons were conducted using least-squares means with Tukey's correction when appropriate.
resultsThe mean scores were KOOS = 96.41 ± 4.79, LKS = 96.41 ± 6.94, and IPAQ-Sf = 1772.02 ± 1332.10. Absolute errors for KJPS angles ranged from 2.58 to 3.42 between genders. KJMS at 60°-90° was measured between 1.82 and 1.95 s in males, and between 1.66 and 1.80 s in females. Significant differences in KJMS (60°-90°) were observed across age groups (F = 14.841, p < 0.001) and position-sense angles (F = 19.645, p < 0.001).
conclusionKJPS assessment revealed significant differences in absolute errors by age and gender. Males demonstrated lower errors, while participants aged ≥ 45 years exhibited greater deviations than younger groups. No gender differences were identified in KJMS. Overall, proprioception declined significantly in the 45+ age group.
