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: This study aims to examine the association of time to recovery between early versus late presentation to outpatient community-based concussion management clinics following sport-related concussion (SRC) among adolescent Canadian athletes. Methods: Using electronic health records (between January 2017 and December 2019) from the Complete Concussion Management Inc (CCMI) database, this was a historical cohort study of Canadian athletes aged 12-18 presenting for care early (0-7 days) or late (8-28 days) after SRC. Time-to-recovery was defined as the date of clinician clearance to return to sport. Propensity scores were first derived from logistic regression with early versus late clinical presentation as the outcome. Cox proportional hazards regression analysis was then used to model the relationship between early versus late clinical presentation and time to recovery, while including the propensity score to adjust for confounding. The association was expressed using hazard rate ratios (HRR) with 95% CIs. Results: A total of 4696 patient records (mean age of 14.71 (±1.69 SD); 57.7% male) were eligible. Early presentation to a concussion management clinic following SRC was associated with faster time to recovery (adjusted HRR 1.23; 95% CI 1.14 to 1.32, p<0.001). This association was consistent within each quintile of the propensity score. The median time to recovery was 18 versus 22 days in the early and late groups, respectively. Conclusion: Adolescent athletes with SRC have favourable recovery trajectories when presenting for care up to 28 days. Time to recovery (clinician clearance to return to sport) may be quicker with an earlier presentation which can lead to a faster return to sport.
