Comparison of the effectiveness and safety between ramicotomy and sympathetic chain interruption in the treatment of primary hyperhidrosis: a meta-analysis.
Synthesis in Clinical autonomic research : official journal of the Clinical Autonomic Research Society, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
objectiveThis meta-analysis evaluates the effectiveness and safety of ramicotomy versus sympathetic chain interruption (SCI) in treating primary hyperhidrosis (PH).
methodsA comprehensive literature search was conducted across multiple databases, including PubMed, Embase, Web of Science, Ovid, Cochrane Library, CNKI, and Wanfang, covering studies from their inception through October 2024. A total of 10 studies involving 970 patients were included, with 504 patients undergoing ramicotomy and 466 receiving SCI.
resultsThe analysis revealed that patients undergoing ramicotomy experienced significantly lower rates of compensatory hyperhidrosis (CH) [odds ratio (OR) 0.41, 95% confidence interval (CI) 0.20-0.85, P = 0.02], severe CH (OR 0.17, 95% CI 0.06, 0.47, P < 0.001), and postoperative hand dryness (OR 0.10, 95% CI 0.01-0.72, P = 0.02), along with a higher recurrence rate (OR 4.03, 95% CI 2.38, 6.85, P < 0.001). No significant differences were observed in operative duration [mean difference (MD) = 0.19, 95% CI -18.23, 18.60, P = 0.98 > 0.05], length of hospital stay (MD = -0.08, 95% CI -0.19, 0.04, P = 0.20 > 0.05), total postoperative complications (OR 0.41, 95% CI 0.07, 2.34, P = 0.32 > 0.05), or surgical satisfaction (OR 0.93, 95% CI 0.45, 1.91, P = 0.83 > 0.05).
conclusionsWhile ramicotomy results in lower incidences of CH and postoperative hand dryness, its higher recurrence rate suggests that its application should be cautious to manage PH effectively.
