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

purposeThe purpose of this study was to determine the clinical success rate of nonoperative treatment of partial-thickness rotator cuff tears (PT-RCTs), to determine baseline clinical factors predictive of outcome of nonoperative treatment of PT-RCTs, and to determine the imaging outcome of nonoperative treatment of PT-RCTs. PATIENTS AND

methodsAll patients with a primary diagnosis of a PT-RCT were eligible for inclusion. Seventy-six patients (48 males, 28 females) with an average age of 52±10 years were included in the study. Patients were evaluated using a standardized format including clinical, imaging, and shoulder specific quality-of-life outcomes. Patients were assessed and treated either successfully nonoperatively or consented to undergo surgical intervention of their PT-RCT. Patients treated nonoperatively underwent follow-up by MRI arthrogram.

resultsThirty-seven patients (49%) underwent nonoperative treatment. Logistic regression analysis indicated that the baseline variables of side (dominant or nondominant side involved), onset (traumatic or atraumatic), and thickness of tendon tear (<50% or >50%) were significant predictors of outcome. At a mean 46±7 months of follow-up, nonoperatively treated patients demonstrated a mean American Shoulder and Elbow Surgeons score of 85.1±16.0, and a Simple Shoulder Test score of 10.0±2.5. Overall, 76% of tears treated nonoperatively did not show a tear progression on anatomic imaging. Nine patients (24%) demonstrated tear progression, of which three patients (8%) demonstrated full-thickness tearing.

conclusionNonoperative treatment was utilized in ~50% of the patients and resulted in improved clinical outcomes. Onset, shoulder involved, and thickness of the tear were predictive of the success of nonoperative treatment.
