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: Due to improved technique and design, bicompartmental knee arthroplasty consisting of patellofemoral joint and unicondylar knee arthroplasty has become a promising alternative to total knee arthroplasty. Advantages include preserving natural knee biomechanics, reducing complication rates, shortening hospital stays, and facilitating faster rehabilitation. This study aimed to assess the survivorship and clinical outcomes for combined medial unicondylar and patellofemoral arthroplasty up to 6 years. Methods: Data on survivorship and patient-reported outcome measures (PROMs) were analyzed retrospectively for 47 patients (mean age: 58.2 years [range: 45 - 78]; mean body mass index: 31.3 kg/m Results: Of the 47 patients enrolled, 7 were lost to FU. The 97.8% survival rate remained consistent throughout the 6-year FU period, following 1 device-related revision within the first 2 years. There was a significant improvement in pain, knee functionality, and patient satisfaction from preoperative to the 1-, 3-, and 5/6-year FUs ( Conclusions: The combined unicondylar and patellofemoral arthroplasty procedure has been shown to achieve excellent survivorship and clinical results up to 6 years after surgery. This makes it an attractive alternative to total knee arthroplasty for patients with medial condylar and patellofemoral knee osteoarthritis.
