Interpretable machine learning for depression recognition with spatiotemporal gait features among older adults: a cross-sectional study in Xiamen, China.
Article in BMC geriatrics, 2025. 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
objectiveDepression in older adults is a growing public health concern, yet there is still a lack of convenient and real-time methods for depressive symptoms identification. This study aims to develop a gait-based depression recognition method for Chinese community-dwelling older adults.
methodsNinety-two participants aged over 60 from Xiamen, China, were recruited for a three-week cross-sectional study. Depressive symptoms were assessed using the 10-item Center for Epidemiologic Studies Depression Scale, with a score of ≥ 10 indicating depression. From each group (depression and non-depression), twenty-five individuals were randomly selected for Kinect-based gait analysis. Gait data were recorded using a Microsoft Kinect in the indoor experimental area. χ
resultsThe average age was 64.1, and 72% were female, with the prevalence of depressive symptoms was 29.34%. Older adults with depressive symptoms exhibited significant gait abnormalities, including reduced body sway (P < 0.01, 95% CI (11.81, 81.79)), right-arm swing (P < 0.05, 95% CI (4.90, 85.07)), left step length (P < 0.05, 95% CI (5.43, 154.32)), right step length (P < 0.05, 95% CI (23.89, 171.36)), left step height (P < 0.001, 95% CI (100.42, 337.85)), walking speed (P < 0.001, 95% CI (245.79, 882.54)), step width (P < 0.05, 95% CI (3.46, 172.34)), and right stride length (P < 0.01, 95% CI (3.99, 25.18)). The Random Forest algorithm achieved the best performance (AUC-ROC = 0.911, Sensitivity = 0.857) in differentiating individuals with or without depressive symptoms based on discriminated spatiotemporal gait features. The five most important gait parameters in the optimal model were left step height, walking speed, right step height, body sway, and step width.
conclusionsSpatiotemporal gait features are associated with depressive symptoms in older adults. The developed machine learning models with high predictive accuracy, suggest the potential of Kinect-based gait assessment as a real-time and cost-effective screening tool for older adults with depressive symptoms.
