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

backgroundPatellar tendinopathy (PT) is a highly prevalent injury among jumping athletes. The long-term prognosis of athletes with PT following physical therapy is unknown. PURPOSE: To assess self-perceived recovery rate and the 5-year change in pain levels, disability, and sports participation, and to explore the prognostic factors associated with self-perceived recovery. STUDY

designCohort study; Level of evidence, 3.

methodsAthletes with PT who were previously enrolled in a randomized trial and received education, load management advice, and exercise therapy instructions at baseline were eligible. An online questionnaire was sent 5 years after inclusion. Self-perceived recovery was assessed by a dichotomized 7-point global rating of change (recovery was defined as "significantly improved" to "completely recovered"). Pain levels during sports (0-10 points) and disability assessed by the Victorian Institute of Sport Assessment-Patellar (VISA-P) score were recorded at baseline and 5 years. Sports participation was categorized into return to performance, return to sport, return to participation, and quitting sports. Nonparametric tests were performed to compare scores at baseline and 5 years. Logistic regression models were used to identify prognostic factors.

resultsOf 76 eligible participants, 58 (76%) responded (mean age, 30 years [SD, 4 years]; 28% female). At a mean follow-up of 5 years, 76% of participants felt recovered. Pain levels during sports (median, 7 points [IQR, 7-8 points] to 2 points [IQR, 1-4 points]) and VISA-P score (median, 57 [IQR, 45-66] to 82 [IQR, 74-97] points) significantly improved from baseline to 5 years (all

conclusionAthletes with PT after physical therapy can expect a generally acceptable long-term prognosis. However, almost one-quarter did not feel recovered and perceived worse patient-reported outcomes. Clinicians treating athletes with PT may use these findings to estimate the average prognosis.
