Double posteromedial portal arthroscopy vs. other arthroscopic techniques for Baker's cyst: a systematic review and meta-analysis.
Review in Frontiers in surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: Double posteromedial portal (DPP) arthroscopy has been proposed to improve cyst management in patients with Baker's cysts compared with other arthroscopic techniques. However, comparative evidence remains limited. Methods: A systematic review and meta-analysis was conducted according to PRISMA guidelines. Comparative clinical studies assessing DPP vs. non-DPP arthroscopic techniques for Baker's cysts were identified from PubMed, Embase, Scopus, Web of Science Core Collection and the Cochrane Library. The primary outcome was cyst recurrence or residual cyst at final follow-up. Secondary outcomes included Lysholm score, operative time, and overall complications. Pooled risk ratios (RRs) or mean differences (MDs) were calculated using fixed- or random-effects models depending on heterogeneity (I²). Sensitivity analyses were performed to assess result robustness. Results: Four comparative studies (all from China; total Conclusion: DPP arthroscopy may reduce cysts recurrence compared with other arthroscopic approaches, but at the cost of longer operative time and higher complication rates. Evidence is limited to small, single-country studies with sparse recurrence events; further multicentre trials are needed.
