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 of this study was to investigate the impact of correction of the reverse shoulder arthroplasty (RSA) angle on clinical outcomes in patients with cuff tear arthropathy (CTA).
methodsThis single-center retrospective study was conducted in patients with CTA treated with RSA between 2013 and 2018. A structured questionnaire collecting demographic data, postoperative follow-up time, pre- and postoperative range of motion (ROM), American Shoulder and Elbow Surgeons (ASES) and Constant functional scores as well as scapular notching according to the Sirveaux Classification and RSA angle were evaluated by independent observers. The association between functional outcomes and RSA angle was analyzed using a curve estimation approach.
resultsSeventy-four patients with a mean age of 69.4 ± 8 years and mean follow-up period of 38.2 ± 10.8 months were included the study. The medialized inlay component was implanted in 35 patients, and the lateralized onlay component was used in 39 patients. The mean preoperative ASES and Constant scores improved from 28.4 ± 5.1 and 31.1 ± 5.9 to 73.4 ± 23.3 and 70.5 ± 16, respectively, at the last follow-up (both P < 0.001). The mean pre- and postoperative RSA angles were measured to be 21.3 ± 9.3° and 5.5 ± 10.1°, respectively, on X-ray. The postoperative RSA angle was 10.4 ± 10.3° in computerized tomography (CT) scans. There was an excellent correlation between X-ray and CT measurements (rs: 0.971, P < 0.001). It was found that patients with good postoperative functional scores tended to have an RSA angle of 0-10° postoperatively. The delta internal rotation of the medialized design group was greater than that of the lateralized design group (P = 0.029).
conclusionIn patients undergoing RSA for CTA, satisfactory clinical outcomes can be obtained by achieving a postoperative RSA angle of 0-10° with an asymmetrical inferior reaming technique. LEVEL OF EVIDENCE: Level III, Therapeutic Study.
