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
Purpose: Golf remains a popular sport after total knee arthroplasty, although many patients report mild pain during or after play, particularly in the lead knee (knee on the target side). Lead knee kinematics during the golf swing are characterised by high tibiofemoral axial rotation at low joint flexion. However, it remains unclear whether the same range of tibiofemoral axial rotation is observed with mobile versus fixed bearing designs. This study aimed to evaluate the influence of two implant designs (mobile-bearing and fixed-bearing) and lead foot rotation (self-selected, 0° and 30° externally rotated) on implant kinematics during the golf swing. Methods: In a total of 11 healthy subjects (five mobile-bearing and six fixed-bearing), kinematic and kinetic data during the golf swing were assessed using videofluoroscopy, an opto-electronic three-dimensional (3D) motion capture system and two force plates. Results: Significantly greater ranges of tibiofemoral axial rotation in the lead knee during the golf swing were observed for the mobile-bearing compared with the fixed-bearing design, independent of foot rotation at the start. Furthermore, the present data showed that a change in foot rotation from a 0° to a 30° externally rotated lead foot increased tibiofemoral axial rotation of the mobile-bearing design but not the fixed-bearing design. Conclusion: The present results suggest that the mobile-bearing design allows a greater range of tibiofemoral axial rotation in the lead knee than the fixed-bearing design during the golf swing, likely due to the differences in internal transverse plane constraints between the two implant designs. However, it remains unclear whether the greater rotation is preferable in terms of longevity and soft tissue loading in total knee arthroplasty patients playing golf. The present data serve as input for musculoskeletal and finite element modelling with the future goal of guiding implant selection and foot positioning recommendations for golf after total knee arthroplasty. Level of Evidence: N/A.
