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

backgroundGuidelines and practices for the management of sport-related concussion (SRC) have evolved swiftly over the past 2 decades. Despite common recommendations for a symptom-free waiting period (SFWP) before returning to sport, past reports have suggested poor utilization rates for this intervention. PURPOSE: To obtain current estimates of the utilization and characterization of SFWPs with high school and collegiate athletes. STUDY

designDescriptive epidemiology study.

methodsData were extracted from a larger prospective study that followed athletes with SRC across 13 institutions in southeastern Wisconsin from 2012 to 2014. Participants included 143 contact and collision sport athletes who were followed serially through their recoveries after SRCs.

resultsIn the current study sample, 99.3% of athletes used an SFWP. The mean self-reported symptom duration was 6.35 days (median, 5 days), with 72.7% reporting symptom recovery within 1 week of injury, 93.7% within 2 weeks, and 99.3% within 30 days. Rate of same-season repeat concussion was low (3.8%) and was similar to or lower than the overall rate of concussion (4.3%). Five same-season repeat concussions occurred at a range of 8 to 42 days after initial injuries.

conclusionIn comparison with prior published data collected from 1999 to 2004, utilization and duration of SFWPs were higher in the current study samples (99.3% vs 60.3% of athletes reported an SFWP; mean duration, 6.1 vs 3.2 days), and athletes were withheld from sports for more days than previously reported (12.3 vs 7.4 days). Rate of same-season repeat concussion was equivalent to that of prior published data. The findings support improved adherence to clinical management guidelines through increased utilization of SFWPs after SRC.
