Quantification of sonographic echogenicity by the gray-level histogram in patients with supraspinatus tendinopathy.
Article in Journal of medical ultrasonics (2001), 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
purposeThe aim of this study was to compare the gray-level value of the supraspinatus tendon of a painful shoulder with that of a normal shoulder measured by ultrasonography, and to investigate whether a low mean gray-level value of the supraspinatus tendon could indicate a partial-thickness or incomplete full-thickness tear.
methodsTwo hundred and ten patients had significant unilateral shoulder pain with the clinical suspicion of rotator cuff tendinopathy. They underwent bilateral shoulder ultrasonography, and the mean echogenicity of the histogram was calculated on the screen. The mean gray-level value of each patient's contralateral asymptomatic shoulder was compared with that of the painful shoulder.
resultsBased on the scan of transverse and longitudinal planes, a significant difference existed between the symptomatic shoulder and contralateral asymptomatic shoulder (p < 0.0001). The mean gray-level values of symptomatic shoulders showed no statistically significant difference between the patients who underwent surgery and the patients who underwent conservative treatment.
conclusionsWe demonstrated that the ultrasound gray-level histogram is a promising tool for detecting the hypoechogenic appearance of supraspinatus tendinopathy. A decrease in the mean gray-level value on the symptomatic shoulder may be used as an alternative sonographic indicator of rotator cuff partial-thickness tear or tendinopathy. LEVEL OF EVIDENCE: Diagnostic level III.
