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

backgroundField-based contact sports, including American football and rugby are among those with the highest sport-related concussion (SRC) rates. Regarding SRC treatment, gradual return-to-play (RTP) protocols are commonly used, however variability in RTP protocols between sporting bodies and scholastic institutions makes accurately interpreting published SRC severity data difficult.

aimsCompare SRC recovery times, RTP protocols, and mandated sit-out period duration among adult amateur contact field sports.

methodsMEDLINE, CINAHL Complete, SPORTDiscus, APA PsycInfo, and APA PsycArticles were searched on May 13th, 2024. Eligibility criteria included (1) published in English in a peer-reviewed journal from 2015 to 2024, (2) adult population, (3) amateur, field-based contact sport athlete population, (4) diagnosed and/or suspected SRC, and (5) recovery time (days/weeks) data available.

results19/6085 (< 1%) studies comprising 58 datasets met all inclusion criteria. The studies comprised American football (10/19, 52.6%), field-hockey (5/19, 26.3%), lacrosse (9/19, 47.4%), ladies gaelic football (1/19, 5.3%), rugby (8/19, 42.1%), soccer (10/19, 52.6%), and sprint football (1/19, 5.2%). Mandated sit-out periods ranged from 0 to 21 days across sports, and RTP protocol durations ranged from 5 to 21 days. The most common RTP protocol duration was 7 days (n = 31/58), and mandated sit-out period was no same-day return (n = 25/58). Field hockey had the longest reported SRC recovery duration (34 days), and rugby had the longest mandated sit-out period (21 days).

conclusionRecovery time following concussion in contact sports should be interpreted in light of sport type, mandated sit-out policies, and RTP protocols. Empirical evidence should drive decisions in RTP protocols and sit-out periods, which are currently inconsistent between sports.
