1 · What the graph read from it

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.

2 · The registry

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

backgroundThe absence of evidence-based guidelines make medical disqualification (MDQ) following concussion one of the most challenging decision-making processes faced by sports medicine professionals.

objectiveWe aimed to compare premorbid and postmorbid factors between student-athletes that were and were not medically disqualified from sport following a concussion.

methodsAmong 1832 student-athletes diagnosed with concussion within the CARE Consortium, 53 (2.9%) were medically disqualified (MDQ +) and 1779 (97.1%) were not medically disqualified (MDQ-). We used contingency tables and descriptive statistics for an initial evaluation of a broad list of premorbid and postmorbid factors. For those factors showing association with MDQ status, we calculated odds ratios and 95% confidence intervals for the odds of being MDQ + in the presence of the identified factor.

resultsHistory of 2 (OR: 3.2, 95% CI 1.5, 6.9) or 3 + (OR: 7.4, 95% CI 3.4, 15.9) previous concussions; 1 + headaches in past 3 months (OR: 1.8, 95% CI 1.0, 3.2); immediate removal from play (OR: 2.4, 95% CI 1.2, 4.9); alcohol (OR: 2.6, 95% CI 1.2, 5.4), tobacco (OR: 3.3, 95% CI 1.1, 9.5), or marijuana use since injury (OR: 5.4, 95% CI 1.5, 19.0); as well as prolonged recovery due to mental health alterations (OR: 5.3, 95% CI 2.0, 14.1) or motivation/malingering (OR: 7.5, 95% CI 3.3, 17.0) increased odds of being MDQ + . The MDQ + group took longer to become asymptomatic relative to the MDQ- group (MDQ + : 23.5 days, 95% CI 15.8, 31.2; MDQ-: 10.6 days, 95% CI 9.5, 11.6; p < 0.001).

conclusionsMDQ following concussion was relatively rare. We identified three patterns related to MDQ following concussion: (1) concussion and headache history were the only premorbid factors that differed (2) initial concussion presentation was more severe and more immediate in the MDQ + group, and (3) post-concussion recovery outcomes expressed the greatest differences between groups.
