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

backgroundReverse total shoulder arthroplasty (RTSA) can lead to limited postoperative internal rotation (IR). We assessed how IR is measured and reported in the RTSA literature and examined the relationships between these measures and patient-reported ability to perform activities of daily living.

methodsWe searched MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials for articles published in English from January 2000 through September 2018 that reported clinical outcomes after RTSA (minimum 12-month follow-up). We included studies reporting IR range of motion (ROM) and/or patient-reported functional outcomes related to IR. We identified 255 studies, 35% of which were excluded because they reported no IR outcome measures, leaving 165 studies for analysis.

resultsStudies reported 3 methods of measuring IR ROM: (1) vertebral level (VL) method (ie, the most proximal VL reached by the extended thumb with the arm behind the back), (2) degrees of IR with the arm abducted to 90°, and (3) degrees of IR with the arm in a neutral position. The VL measurement was reported in 89% of studies, but the methods of reporting this measure varied. Only 9% of studies reported functional outcomes related to IR. No study correlated clinical measurements of IR ROM with functional outcomes.

conclusionsMeasures and reporting of shoulder IR after RTSA varied widely. This variability makes it difficult to assess associations between postoperativce IR limitation and functional abilities. Standardization of IR measures and reporting is needed to allow meta-analysis of data related to this important outcome.
