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

purposeThoracic hyperkyphosis, an extrinsic cause of subacromial impingement syndrome (SIS), can contribute to a decrease in the acromio-humeral distance (AHD). Thoracic mobility is necessary to reduce pain and maintain function during shoulder elevation. The aim of this study was to investigate the effect of thoracic mobilization on AHD, thoracic kyphosis angle, pain, and shoulder function in patients with SIS.

methodsThirty-two patients with SIS, aged between 25 and 50 years, were included in the study. The exercise group (EG) performed the home exercises (rotator cuff and scapulothoracic joint-based exercises) for 12 weeks. The thoracic mobilization group (TMG) received thoracic mobilization for the first 6 weeks in addition to the same exercise program. AHD was assessed with ultrasonography, thoracic kyphosis angle with the Goniometer-pro, pain intensity with a visual analog scale (VAS), and shoulder function with American Shoulder and Elbow Surgeons (ASES) at before treatment, and follow-up at 6-week and 12-week.

resultsThe TMG had a greater increase in AHD at 60º and 90º (at 60º;6th weeks, p = 0.000; 12th weeks, p = 0.000, at 90º;6th weeks, p = 0.048;12th weeks, p = 0.000) and shoulder function (6th weeks, p = 0.000;12th weeks, p = 0.000) and a decrease in thoracic kyphosis angle (6th weeks, p = 0.002;12th weeks, p = 0.000) and pain intensity in night and activity (night pain;6th weeks, p = 0.000;12th weeks, p = 0.042, activity pain;6th weeks, p = 0.000;12th weeks, p = 0.000) than the EG both at 6th and 12th weeks.

conclusionThoracic mobilization applied in addition to the rotator cuff and scapulothoracic joint-based exercises was found to be more effective in increasing AHD and shoulder function in patients with SIS and reducing pain intensity and thoracic kyphosis angle.
