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/objective: Although many studies have reported the clinical outcomes of pullout repair for medial meniscus posterior root tears (MMPRTs) or microfractures for focal cartilage lesions alone, no study has specifically reported the clinical outcomes in patients with MMPRT combined with cartilage lesions. Therefore, we investigated the effectiveness of bone marrow stimulation via microfracture for treating focal cartilage lesions associated with MMPRT and compared the clinical outcomes between patients who underwent microfracture and those who did not. We hypothesised that favourable clinical outcomes could be achieved after transtibial pullout repair combined with microfracture for MMPRTs with focal cartilage lesions and that these outcomes would be comparable to those after transtibial pullout repair alone for MMPRTs without cartilage lesions. Methods: Ten patients who underwent transtibial pullout repair and microfracture for MMPRT with cartilage lesions (Group MF) and 37 patients who underwent only pullout repair for MMPRT without cartilage lesions (Group P) using the same pullout technique (two simple stitches) as Group MF between November 2016 and September 2023 were retrospectively evaluated. The age at the time of surgery, sex, height, weight, body mass index, duration from injury to surgery, and KL grade were recorded for each patient. The presence, location, and area of cartilage lesions were evaluated. Clinical outcomes were assessed, and all included patients underwent a second-look arthroscopy. Results: The mean follow-up period, patient age, body mass index, femorotibial angle, and percentage of the mechanical axis in Group MF were 3.2 years, 60.2 years, 26.1 kg/m Conclusion: The clinical outcomes of transtibial pullout repair combined with microfracture were favourable in patients with MMPRT and focal cartilage lesions in well-aligned knees. Moreover, no significant differences in clinical outcomes were detected between patients who underwent pullout repair combined with microfracture and those who underwent pullout repair alone. MMPRTs with focal cartilage lesions may be effectively treated with pullout repair combined with microfracture, provided that strict patient selection criteria are applied.
