Efficacy and safety of ultrasound-guided percutaneous microwave ablation for hepatocellular carcinoma at specific anatomic sites of the liver: a systematic review and meta-analysis.
Article in Frontiers in surgery, 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
Objective: This meta-analysis aims to assess the efficacy and safety of ultrasound-guided percutaneous microwave ablation (MWA) in the treatment of hepatocellular carcinoma (HCC) located at specific anatomic sites of the liver with those of non-specific sites. Methods: A systematic search was conducted across five databases, covering the period from the establishment of each database to September 30, 2024. Prospective and retrospective studies involving ultrasound-guided percutaneous MWA for the treatment of HCC were included. Data extraction and statistical analysis were performed using Stata 15.1 software. The main outcomes were 1-year, 3-year, and 5-year overall survival rates, complete ablation rates, and major complication rates. The results were presented as odds ratios (OR) with 95% confidence intervals (CI). Results: A total of 9 studies were included, involving 2,381 patients, of which 1,047 had HCC at specific anatomic sites, and 1,334 had HCC at non-specific sites. The OR values (95% CI) for overall survival at 1 year, 3 years, and 5 years for patients with HCC at specific anatomic sites compared to non-specific sites were 0.89 (0.59, 1.35), 0.83 (0.66, 1.05), and 1.12 (0.91, 1.38), respectively. The OR for complete ablation rate was 0.97 (0.61, 1.53), and the OR for major complications was 1.44 (0.59, 3.51). Conclusion: Ultrasound-guided percutaneous MWA for HCC at specific anatomic sites shows similar efficacy and safety to that at non-specific sites, with no significant differences in survival rates, complete ablation rates, or complication rates.
