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: The application of the Sub-vastus (SV) approach in Robot-assisted total knee arthroplasty (RATKA) is a relatively new practice with many potential benefits. This study aimed to assess the cases that underwent robot-assisted knee replacement through the sub-vastus approach, using functional and clinical parameters. Methods: This monocentric, single-surgeon, retrospective observational study included 81 consecutive cases (120 knees) who had undergone Robot-assisted total knee arthroplasty with the Sub-vastus approach. Their Postoperative evaluation included hemoglobin levels, functional outcomes like the straight leg raising test (SLRT), walking ability, and the Oxford Knee Score (OKS). Results: The average age of participants was 63.3 years. The mean hospital stay was 3.4 days (median 3 days). Perioperative drop in Hemoglobin concentration averaged 1.27 g/dl for unilateral and 1.5 g/dl for bilateral cases. By the second postoperative day, 85 % of the study group were able to perform active straight leg raising and 66 % were able to walk with support. These numbers increased to 95 % by the third day. The mean OKS was 45.832 (SD: 1.29). Conclusion: The SV approach, when combined with RATKA, can yield improved functional results by showing the short-term benefits of a quadriceps-sparing technique, like less blood loss, faster recovery, and shorter hospital stay, while also enhancing surgical precision and accuracy in implant placement, thereby improving longevity. This combination is also effective in addressing severe deformities and obese cases, which previously were a limitation of the SV approach. Incorporating an oblique under-vastus release of the suprapatellar pouch and capsule was found to facilitate surgical access and may enhance procedural efficiency.
