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 shoulder is a commonly injured area in hockey, yet information is lacking on the prevalence and effect of shoulder instability. Our study investigates the incidence of shoulder dislocation events in the National Hockey League (NHL) and the effects on return-to-play (RTP) and player performance. We hypothesize that NHL players would have high RTP rates without significant changes in performance after injury.

methodsNHL players who suffered in-season shoulder instability events between 2003-2004 and 2017-2018 seasons were identified. Demographic characteristics, incidence of injury, recurrences, RTP, and statistical performance data were collected. Postinjury performance was compared with experience-matched, era-matched, position-matched, and age-matched controls. A mixed generalized linear regression model was used to compare postinjury performance as a function of operative and nonoperative treatment.

resultsA total of 57 players experienced 67 shoulder instability events with 98.5% of players returning to play after an average of 26.3 ± 20.8 regular season games missed. Surgery was performed in 47.8% of players with no recurrent injuries postoperatively. Nonoperatively managed players experienced a decrease in points per game (

conclusionProfessional hockey players experience high rates of RTP with acceptable performance outcomes after shoulder instability events; however, recurrent injuries led to significantly more career games missed when treated nonoperatively at the time of injury.
