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
purposeTo assess the safety, effectiveness, and postoperative outcomes of medial collateral ligament (MCL) pie-crusting (PC) in arthroscopic meniscus surgery.
methodsThis systematic review was conducted in accordance with PRISMA guidelines. Three databases (PubMed, EMBASE and MEDLINE) were searched from inception to 21 January 2025, for studies evaluating the use of MCL PC during arthroscopic meniscus or anterior cruciate ligament (ACL) surgery. Data on patient demographics, medial joint space measurements, postoperative instability, patient reported outcome measures (PROMs), and complications were extracted.
resultsFifteen studies comprising 1009 patients were included, with 723 undergoing PC. PC significantly increased medial joint space width by a mean of 5.7 mm intraoperatively (p < 0.05), with no residual laxity reported at mean final follow-up of 16.5 months. The most common complications of PC were transient medial knee pain (12.7%) and ecchymosis (12.9%). There were five reports of saphenous nerve irritation (0.8%), all resolved by final follow-up of 31.6 months. In contrast, iatrogenic chondral injury was reported in 9.0% of patients undergoing meniscal repair without PC.
conclusionMCL PC is a safe and effective technique to improve visualisation and outcomes in arthroscopic meniscus surgery. It is associated with improved joint access and low complication rates without long-term instability. While current evidence supports its use, further high-quality, long-term comparative studies are needed to validate its safety and efficacy, as this study primarily used retrospective data without long-term follow-up. LEVEL OF EVIDENCE: Level IV.
