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 aim of this study was to analyse the clinical and radiographic results of 208 e-Motion® posterior cruciate-retaining, mobile bearing prostheses (BBraun-Aesculap, Tuttlingen, Germany) fitted using computer navigation, for knee osteoarthritis with a genu varum greater than 10°.
methodsOne hundred ninety-two patients were operated on with 208 e-Motion® prostheses fitted, between January 2006 and December 2011, using the OrthoPilot® computer navigation system. Average pre-operative IKS score was 70 ± 27 points (6-143) with a function score of 38 ± 20.5 (0-90) and a knee score of 32.5 ± 13 (0-63). Average flexion was 116.5° ± 13° (65-140°). Average pre-operative HKA angle was 166° ± 3° (154-169°).
results2Results are available for 134 patients, with a total of 150 knees operated on (38 lost to follow-up and 20 deceased). Average follow-up was 104.5 months (60-116 months). On last follow-up, the average IKS was 180 ± 22 points (95-200) with 86.5 ± 16 points (25-100) for the function score and 93.5 ± 8 points (55-100) for the knee score. Knee flexion was 116° ± 10.5° (80-135°) and average HKA angle was 179° ± 2° (175-184°). The pre-operative objective was achieved in 90.5% of knees.
conclusionThe e-Motion® mobile bearing posterior cruciate-retaining prosthesis, fitted using computer navigation, offers excellent results after an average of 8.5 years follow-up. These results are at least equivalent, even superior, to those of the posterior-stabilised prostheses usually used for this type of deformity.
