Characteristics of acromial morphology in patients with painful shoulders from Indonesia.

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
backgroundShoulder pain is a common reason for patients to seek care from general practitioners or orthopaedic specialists. Prior studies suggest a correlation between acromial morphology and shoulder pathologies. This study aimed to determine acromion characteristics in the Indonesian population and evaluate associations between acromion type, radiographic parameters, sex, and shoulder disorders.
methodsA cross-sectional study was conducted on 487 patients with shoulder disorders, using consecutive sampling and data from our institution's radiology database (2020-2021). Acromion morphology was classified using the Bigliani system. Diagnoses were based on clinical and radiological records. Radiographic parameters assessed included critical shoulder angle (CSA), acromion index (AI), lateral acromial angle (LAA), acromioclavicular (AC) joint distance, acromiohumeral (AH) joint distance, and acromial tilt.
resultsAmong 487 patients, type II acromion was most common (59.5%), followed by type I (33.3%), type IV (4.5%), and type III (2.7%). Mean CSA was 38.36 ± 5.13, AI 0.72 ± 0.09, LAA 72.52 ± 6.01, AC joint distance 3.18 ± 0.89, AH distance 8.61 ± 1.86, and acromial tilt 28.84 ± 4.52. No significant association was found between acromion type and shoulder disorders (p = 0.34), or between sex and acromion type (p = 0.516). Radiographic parameters also showed no significant correlation with shoulder disorders.
conclusionType II acromion was the most prevalent in this Indonesian population. No significant associations were observed between acromion type, sex, or radiographic parameters and shoulder pathologies. Acromial morphology may represent normal anatomical variation rather than a pathological finding.
