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

objectiveRotator cuff retear after arthroscopy repair is a difficult complication that is often due to poor tendon-bone healing. Decellularized amniotic membrane (DAM) has a variety of bioactive substances which have great potential to enhance tendon-bone healing. However, DAM has three layers, of which the middle basement layer is dense and thick. Whether DAM will hinder tendon-bone healing of rotator cuff after surgical repair is unclear. Our study aims to investigate the effect of DAM on tendon-bone healing of the rotator cuff after surgical repair.

methodsThirty-three Sprague-Dawley (SD) rats were selected to establish unilateral supraspinatus (ST) tear models and were randomly treated with only suturing repair (OSR group, n = 11), and suturing repair with DAM placed between the ST and bone (DAM group, n = 11). In the normal control group (NCT group, n = 11), the supraspinatus was only exposed but not detached or repaired. After 4 weeks the rats were sacrificed. The assessment of specimens was conducted by micro-CT analysis, histopathological evaluation, and biomechanical testing.

resultsThe DAM group had a significantly higher ultimate load to failure, new bone volume, and histological evaluation at 4 weeks after surgery than the OSR group. When comparing the DAM group to the NCT group, the DAM group performed slightly worse in biomechanical testing, micro-CT analysis, and histological evaluation.

conclusionWhen placed between tendon and bone at the rotator cuff footprint, DAM, despite its dense and thick basement layer, does not impede tendon-bone healing after surgical repair for rotator cuff injury, but rather promotes increased healing quality and biomechanical properties. However, the healing quality and biomechanical properties are still lower than that of the normal rotator cuff, and further improvement should be made to the application strategy of a DAM.
