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: The Ankle-GO score is an objective battery for return-to-sports (RTS) decision-making after nonoperative or surgical treatment in patients with chronic ankle instability (CAI). However, direct comparisons of Ankle-GO subscales between CAI patients with and without successful RTS are limited, and predictors of successful RTS remain unclear. Purpose: To directly compare the Ankle-GO subscales between CAI patients with and without successful RTS after nonoperative treatment and modified Broström operation (MBO) and to explore which Ankle-GO subscales are significantly associated with successful RTS. Study Design: Case control study; Level of evidence, 3. Methods: A total of 100 patients (100 ankles) with CAI were enrolled. Of these, 52 ankles underwent nonoperative treatment (31 with successful RTS and 21 without) and 48 ankles underwent MBO (26 with successful RTS and 22 without). Successful RTS was defined as return to preinjury sport level with a Tegner activity score ≥6. The Ankle-GO, which consists of 6 subscales, was compared between patients with and without successful RTS: the single-leg stance test, modified star excursion balance test, side hop test (SHT), figure-of-8 test (F8T), Foot and Ankle Ability Measure, and Ankle Ligament Reconstruction-Return to Sport after Injury (ALR-RSI). Statistical analyses were performed using independent Results: In the nonoperative treatment group, CAI patients with successful RTS demonstrated superior Ankle-GO scores, SHT, and F8T compared with those without successful RTS (all Conclusion: Our study demonstrated that in both the nonoperative treatment and MBO groups, SHT and F8T were key factors distinguishing patients with CAI who had successful RTS from those who did not. In addition, SHT was the strongest independent predictor of RTS in both the nonoperative treatment and MBO groups. Clinicians and therapists should consider these findings when planning rehabilitation and RTS strategies.
