Femoral components are positioned in greater external rotation using functional alignment in robot-assisted total knee arthroplasty compared to mechanical alignment.

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: Objective of this study was to evaluate the effect of functional alignment on femoral component rotation compared to mechanical alignment in knees with a constitutional tibial varus alignment classified as coronal plane alignment of the knee (CPAK) types I, II and IV. Methods: This retrospective study included patients undergoing conventional total knee replacement (TKR) ( Results: Femoral component rotation was statistically significant more external rotated in the conventional group versus robot-assisted group (1.3° ± 2.7° vs. 0.76° ± 1.4°, Conclusion: Functional alignment leads to more varus of the tibial component and less external rotation of the femoral component compared to mechanical alignment in TKR in patients with a constitutional tibial varus alignment. Since this is a radiological analysis, further research is needed to understand how these differences affect clinical outcomes as faster recovery, adequate patellar tracking and longer survival. Level of Evidence: Level III.
