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
backgroundTibial rotational alignment is the most prone to error among the placement angles of the prosthesis in total knee arthroplasty (TKA). The augmented reality (AR)-aided navigation system enables surgeons to visualize the tibial anteroposterior axis established on the pre-resection surface superimposed on the bone surface after proximal tibial resection.
methodsWe compared the axial, coronal, and sagittal alignments of the tibial baseplate between 58 TKAs performed using an AR-aided navigation system and 64 TKAs in which the rotational alignment was determined manually. To assess alignment, the three-dimensional coordinates of the lower limb from preoperative CT data were overlaid onto postoperative CT data using a surface-matching algorithm.
resultsThe absolute difference between the anteroposterior axis and the rotational angle of the tibial baseplate was significantly smaller in the AR-aided group compared to the control group (3.7 ± 3.4° vs. 5.1 ± 4.4°, p = 0.047). In both coronal and sagittal alignments, the absolute differences between the target angle and the measured angle were not significantly different between the two groups (1.1 ± 0.9° vs. 1.2 ± 1.0°, p = 0.75 in coronal alignment, and 1.9 ± 1.3° vs. 1.7 ± 1.4°, p = 0.43 in sagittal alignment, respectively).
conclusionsThe AR-aided navigation system slightly but significantly improved the accuracy of tibial rotational alignment.
