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
purposeThis study aims to compare the duration of surgery and fluoroscopy exposure between the supine and beach-chair positions during antegrade intramedullary nailing (IMN) of humeral shaft fractures.
methodsA retrospective, single-center study was conducted at a German Level I Trauma Center from January 2021 to August 2024. Patients included were aged 18-95 with confirmed humeral shaft fractures diagnosed via radiographic imaging. Exclusion criteria comprised fractures older than two weeks, polytrauma cases, concomitant neurovascular injuries, and patients undergoing alternative osteosynthesis procedures during the same surgery. Surgery was performed in either the supine or beach-chair position, and comparisons were made regarding operative duration, fluoroscopy time, and radiation dose exposure. Furthermore, the influence of fracture complexity (A-,B- and C- fractures according to AO) on these three parameters was tested. Demographic data were also collected and analyzed.
resultsA total of 79 patients were initially considered, with 59 meeting the inclusion criteria after the exclusion of 20 polytrauma cases. The final cohort consisted of 25 males (42.4%) and 34 females (57.6%), with a mean age of 67.1 years (± 20.1) and a mean BMI of 25.6 (± 5.6). Surgical outcomes demonstrated that procedures performed in the beach-chair position were significantly longer (103.5 ± 54.0 min) compared to those in the supine position (89.0 ± 42.0 min, p = 0.023). Furthermore, radiation exposure was considerably lower in the supine position (1,0 centigray/cm
conclusionSupine positioning for antegrade IMN of humeral shaft fractures significantly reduces both operative duration and radiation exposure compared to the beach-chair position, whereas fracture complexity does not significantly influence these parameters. The findings suggest that the supine position offers a viable alternative for patient positioning in these procedures.
