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
Background: Hip osteoarthritis (OA) is a degenerative joint disease that predominantly affects the elderly, causing significant morbidity due to joint pain, stiffness, and loss of function. This study aimed to assess the limits of stability (LOS) using computerized posturography and evaluate the correlations with functional mobility in elderly individuals with hip OA. Methods: This cross-sectional study included elderly individuals aged 65 years and above with a clinical diagnosis of hip OA and age-matched asymptomatic controls. The LOS was measured using a computerized dynamic posturography system, which quantified the maximum distance and angle participants could shift their center of gravity without losing balance. Functional mobility was assessed using the Timed Up and Go (TUG) test, which measures the time taken for participants to stand up, walk 3 m, turn around, walk back, and sit down. Results: The study included 86 elderly individuals with hip OA and 86 age-matched asymptomatic controls. LOS assessments showed that individuals with hip OA had significantly lower stability scores across all directions compared to controls (p < 0.001). TUG test times were significantly slower for the OA group (10.50 ± 2.20 s) compared to controls (8.70 ± 2.00 s, p < 0.001). Positive correlations were found between LOS and functional mobility (r = 0.50, p = 0.009). Moderation analysis revealed that age and duration of OA significantly influenced the relationship between stability and mobility. Conclusion: Hip OA significantly impacts stability and functional mobility in elderly individuals. Enhanced stability is associated with improved mobility, and demographic and clinical variables such as age and duration of OA play crucial roles in these relationships. These findings underscore the importance of targeted therapeutic interventions to improve stability and mobility in this population.
