Radiographic findings in patients suspected of subacromial impingement syndrome in relation to shoulder pain and disability.

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
objectiveThe aim was to study the association between specific radiographic findings and patient reported shoulder pain and disability in patients suspected of subacromial impingement syndrome (SIS). MATERIALS AND
methodsThis cross-sectional study used baseline data from a prospective study. Study population included patients age 18 to 63 years, referred to orthopaedic clinic on suspicion of SIS. Radiographic findings before first visit to a department of orthopaedic surgery comprised subacromial calcifications, acromial morphological characteristics (i.e. acromial type and spur), acromioclavicular osteoarthritis, signs of previous glenohumeral dislocation (Bankart/Hill-Sachs lesions), and architectural measures (i.e. acromial tilt, acromion index, and lateral acromial angle). Shoulder pain and disability were evaluated using the Oxford Shoulder Score (OSS) from patient's response to a questionnaire at first visit to the public department of orthopaedic surgery or before surgery for SIS. A low OSS was defined as having a score < 25. Associations between the radiographic findings and low OSS were analysed using logistic regression.
resultsThe population comprised 825 patients. Median time between radiographic examination and completion of the questionnaire was 9 days (SD = 27.1). In adjusted analysis, we found a statistically significant association for lateral spur especially birdbeak type (OR = 2.24 (95% CI 1.36-3.71)), Bankart/Hill-Sachs lesion (OR = 2.49 (95% CI 1.38-4.48)), and acromial tilt > 35° (OR = 0.62 (95% CI 0.41-0.94)). Female sex (OR = 2.25 (95% CI 1.59-3.18)) was also associated with low OSS.
conclusionIn terms of associations with patient-reported shoulder pain and disability, lateral spurs, with emphasis on birdbeak type, Bankart/Hill-Sachs lesions, and acromial tilt > 35°, seemed clinically important.
