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
Background: Younger and more active patients undergoing primary cemented total knee arthroplasty (TKA) have demonstrated increased failure incidence due to multiple factors including aseptic loosening. The purpose of this study was to evaluate results of cementless TKA using a highly porous cementless tibial baseplate in patients aged ≤50 years. Methods: This was a retrospective study of 150 consecutive cementless TKAs in patients aged ≤50 years using the same implant design. Twenty-nine patients were lost-to-follow-up (19.3%), leaving 121 TKAs in 98 patients with minimum 5-year follow-up. There were 41 men and 80 women with mean age of 45.8 years (range, 32-50), mean BMI of 37.5 kg/m Results: There were 11 (9.1%) revisions: 5 (4.1%) for instability, 4 (3.3%) for dissociation of the metal-backed patella from the polyethylene, and 2 for unexplained pain elsewhere. Knee Society function and knee scores improved from means of 46.6 and 39.3 preoperatively to 79.9 and 83.3 postoperatively, respectively ( Conclusions: Cementless TKA utilizing a highly porous baseplate in patients aged ≤50 years with mean 7.6-year follow-up demonstrated excellent survivorship with no revisions due to aseptic loosening. Results of this study using a cementless highly porous tibial baseplate with the advantage of biological fixation appear promising.
