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 Gamma3 nail (Stryker®) is an intramedullary device consisting of a proximal lag screw and distal interlocking screw. It is still unknown whether the screw locking mode could influence clinical outcomes. The aim of this study is to compare static and dynamic screw locking regarding their influence on surgical revisions and lag screw displacement.
methodsA retrospective single-centre study was performed on patients ≥ 60 years admitted for a trochanteric fracture between September 2016 and January 2020. Surgical revisions and lag screw displacement were evaluated at 6 weeks and 1-year follow-up, respectively.
resultsA total of 142 patients were included for analysis. Surgical revisions were needed in 13 cases (9.2%). Indications included implant breakage (n = 3), lag screw cut-out (n = 3), lateral hip pain (n = 6) and non-union (n = 1). The number of surgical revisions was not different between static and dynamic locking (OR 2.55; 95%CI 0.73-8.56; p 0.142). The median lag screw displacement was 2.5 mm, which was similar for static and dynamic locking (2.3 mm versus 2.7 mm; p 0.785).
conclusionThe screw locking mode of the Gamma3 nail is not associated with a higher risk of surgical revisions. However, the design of the Gamma3 nail may not be suitable for static locking.
