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

objectiveTo describe and predict patient-reported outcomes (PROs) and to investigate differences between individuals with a rotator cuff tear who were and were not successfully treated with a 12-week exercise therapy program.

designProspective observational cohort.

settingOrthopedic sports medicine clinical practice settings and departments of orthopedic surgery, physical therapy, and bioengineering at the University of Pittsburgh.

participantsEighty-two individuals, age ≥40 years with a symptomatic isolated supraspinatus tear.

interventionsIndividualized 12-week exercise therapy program and longitudinal follow-ups at 3, 6, 12, and 24 months.

main outcome measures(1) PROs: Western Ontario Rotator Cuff (WORC) index (WORC) & Numeric Pain Rating Scale (NPRS), (2) shoulder range of motion (ROM) and strength, (3) rotator cuff tear size and location, (4) glenohumeral kinematics.

resultsSignificant improvements in both PROs were observed at all time points when compared with baseline. At the 24-month follow-up, improvement greater than the minimally clinically important difference was noted for 78% of individuals for the WORC and 55% for the NPRS. Baseline predictors for 24-month change in WORC and an overall successful outcome were identified and included the baseline WORC score and the side-to-side difference in ROM for external rotation at 90 degrees abduction.

conclusionsIndividuals with symptomatic, isolated supraspinatus tears, managed with exercise therapy, experienced clinically important improvements in self-reported disability and more than half experienced a similar improvement in pain, at a 2-year follow-up. Baseline patient-reported outcomes measures and side-to-side differences passive ROM predicted 24-month success after exercise therapy. These findings may be useful in plan-of-care decision making.
