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.

Abstract

backgroundPartial supraspinatus tendon tears have frequently been treated using a subacromial corticosteroid injection or surgery. The clinical use of a platelet-rich plasma (PRP) injection is an alternative treatment method for the condition, despite the paucity of evidence of its efficacy. PURPOSE: To compare pain relief, functional improvement, and complications after an intratendinous PRP injection versus a subacromial corticosteroid injection for partial supraspinatus tears. STUDY

designRandomized controlled trial; Level of evidence, 1.

methodsA total of 32 patients with partial supraspinatus tears were randomly assigned to receive a leukocyte-poor PRP (LP-PRP) injection or a corticosteroid injection. One patient withdrew from the PRP group, leaving 15 patients in the PRP group and 16 patients in the corticosteroid group. The ultrasound-guided procedures were performed by a single experienced pain physician. Pain relief and functional improvement were evaluated using the visual analog scale (VAS) and the Oxford Shoulder Score (OSS), respectively. Treatment efficacy and complications were documented, and the 2 groups were compared at 1- and 6-month follow-up.

resultsThere were no differences in VAS and OSS scores between the PRP and corticosteroid groups at 1-month follow-up. However, the PRP group had better scores than the corticosteroid group had on both the VAS and OSS at 6-month follow-up (VAS: 14.5 ± 15.4 vs 37.5 ± 24.9, respectively; OSS: 16.2 ± 3.9 vs 25.0 ± 10.2, respectively;

conclusionAn injection using either a corticosteroid or LP-PRP resulted in a similar reduction in pain and improvement in function at 1 month in patients with a partial supraspinatus tear. However, PRP showed superior benefits over the corticosteroid at 6-month follow-up.
