Comparative study of the Karydakis flap versus conventional surgical techniques for pilonidal sinus disease: a systematic review and meta-analysis.
Synthesis in Updates in surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Not yet cited in PubMed.
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
The ideal surgical treatment for pilonidal sinus disease (PSD) is controversial. The Karydakis flap (KF) was compared with midline closure (MC) and excision with healing by secondary intention (EHSI). A systematic review and meta-analysis of randomised and comparative cohort studies (through February 2025) was performed. The primary outcomes included recurrence and infection, whereas secondary outcomes were seroma, operative time, hospital stay, overall complications, and return to work. The effect sizes were identified using odds ratios (OR) or mean differences (MD) with 95% confidence intervals (CI), using random-effects models. Fifteen studies (n = 3,108) were identified for inclusion (KF = 1,257, MC = 1,593, EHSI = 258). KF was associated with a significant reduction in recurrence compared to MC (OR 0.30, 95% CI 0.16-0.59; p < 0.001; I
