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.
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
purposeRotator cuff (RC) tears are common in older adults, often leading to muscle atrophy. Standard arthroscopic repair has high re-tear rates, prompting the use of biological patches for augmentation. This study assessed differences in range of motion, strength, and tendon healing using ultrasound in primary and revision RC repairs using acellular dermal allograft augmentation.
methodsForty-eight patients undergoing arthroscopic RC repair with dermal allograft augmentation were assessed, with 42 completing a median follow-up of 32.4 months. Twenty patients had primary repairs and 22 had revision procedures. A control group of 26 patients, matched for age, sex, BMI, and RC injury type, underwent RC repair without patch augmentation. Active range of motion, Constant-Murley socre (CS), Simple Shoulder Test (SST), Subjective Shoulder value (SSV) and isometric strength were measured. Tendon healing was assessed via dynamic US.
resultsBoth primary and revision groups showed significant improvements in clinical scores and shoulder mobility. However, the primary group had significantly higher postoperative CS, SST and SSV scores. Strength tests indicated lower values in the revision group compared to primary and control groups. Ultrasound outcomes showed reduced tendon thickness in 23 patients, with similar repair integrity across groups. Five cases of RC re-tears were noted, with higher but not significantly different re-tear rates in the revision group.
conclusionDermal allograft augmentation in RC repair leads to significant clinical improvement in both primary and revision cases, but strength recovery is less pronounced in revision repairs. Long-term follow-up is necessary to validate these findings and assess the durability of tendon healing. LEVEL OF EVIDENCE: Level III, Retrospective cohort design, Treatment study.
