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
Despite promising results of kinematic alignment (KA), there are still concerns regarding the wear behavior of KA knee implants. In a previous study, mechanically aligned (MA), KA and malaligned (MalA) knee implants were tested in a wear simulation study using Attune knee implant systems. The results showed no increased wear rate for a mild KA (KA4°) and MalA (MalA4°) condition in comparison to MA (MA0°) knee implants. This study analyzes the wear behavior of a KA condition of 8° (KA8°). The test setup was adapted accordingly. In addition, all tests of the previous study (MA0°, MalA4° and KA4°) and the KA8° condition were replicated using PFC implant systems to indicate if the previous results can be transferred to the predecessor model of the Attune knee implant system. The KA8° using the Attune knee implant system did not lead to a higher wear rate (2.4 ± 0.1 mg/10
