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

introduction/purposeCurrently there is little evidence supporting the use of objective tests, measures, or imaging to help predict time to return to sport (RTS) following a hamstring strain. The purpose of this study is to investigate the predictive value of tenderness to palpation (TTP) as measured by area and location following hamstring strain. STUDY

designCase Series.

methodsNineteen male athletes (age 28 ± 9 yr) who sustained an acute hamstring strain underwent hamstring tenderness mapping on initial evaluation. The length and width of tenderness of the hamstring was identified with manual palpation, outlined in pen, and was then calculated as a percentage of the length and width of the posterior thigh. All patients underwent the same hamstring rehabilitation protocol with remapping performed at specific stages in rehabilitation. The association between mapping tenderness indices and RTS was assessed by linear regression.

resultsThe average length of the area of tenderness was 22 ± 12% with an average RTS of 43 ± 36 days. The length of the area of tenderness measured on initial evaluation was a strong predictor of RTS (R

conclusionsThe length of the area of tenderness to palpation of the injured hamstring muscle was highly predictive of RTS time. Based on the regression equation a patient with a length of tenderness of 10% would have an estimated RTS time of 17 days, while a tenderness length of 30% would be estimated to return in 63 days. This hamstring mapping technique described was predictive of the RTS and may be a useful clinical tool. LEVEL OF EVIDENCE: IIb.
