Effects of Tai Chi Chuan on Postural Stability and Lower-Limb Biomechanical Characteristics in Patients With Functional Ankle Instability: A Randomized Controlled Trial.

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
Objectives: To evaluate the effects of a 12-week Tai Chi Chuan (TCC) program on ankle instability/function, pain, and gait/balance performance in patients with functional ankle instability (FAI). Design: Prospective, single-blind randomized controlled trial. Setting: Clinical gait analysis laboratory with community-based recruitment. Participants: Fifty patients with FAI were randomly divided 1:1 to a TCC group (n=25; age 65.44±8.75y; 18 women/7 men) or a control group (n=25; age 67.08±4.76y; 22 women/3 men). By eligibility criteria, all participants had experienced at least 1 severe ankle sprain within the prior year and had recurrent episodes of giving way/instability in the prior year. Interventions: The TCC group completed supervised simplified 24-form TCC training 3 sessions/wk for 12 weeks; controls received structured health education once every 4 weeks for 12 weeks. Main Outcome Measures: The primary outcome was the Cumberland Ankle Instability Tool (CAIT). Secondary outcomes included the American Orthopaedic Foot & Ankle Society Ankle-Hindfoot Score, pain intensity (visual analog scale [VAS]), 3-dimensional gait spatiotemporal and sagittal kinematic parameters, and postural control (Huber360 static balance metrics and the Y-Balance Test [YBT]). Results: After 12 weeks, CAIT increased by 10.32 points in the TCC group (14.48±5.53 to 24.80±4.21) compared with 2.84 points in the control group (15.16±5.98 to 18.00±5.05), with a significant between-group difference ( Conclusions: A 12-week TCC program may provide clinically meaningful improvements in ankle stability and function, reduce pain, and enhance gait and balance performance in patients with FAI.
