Safety and efficacy of carbon dioxide laser therapy for vocal cord leukoplakia: A systematic review and meta-analysis.

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
backgroundVocal cord leukoplakia is a precancerous lesion for which early surgical intervention following ineffective conservative treatment is the predominant approach. Carbon dioxide (CO2) laser treatment is a novel, minimally invasive therapy. However, there is insufficient evidence to suggest that CO2 laser treatment is superior to conventional surgical methods in terms of efficacy and safety. Therefore, this meta-analysis aimed to evaluate the efficacy and safety of CO2 laser treatment vs conventional surgical treatment for vocal cord leukoplakia.
methodsA literature search was conducted using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines across 8 databases. Studies on the use of carbon dioxide laser therapy for vocal cord leukoplakia were included in the review. Two researchers conducted a systematic search for randomized controlled trials in PubMed, Embase, Cochrane, Web of Science, China National Knowledge Infrastructure, Wanfang, Chinese Science and Technology Periodical Database, and Chinese Biomedical Literature databases. Meta-analysis was performed using Stata 18.0, and RevMan 5.2 software.
resultsThe findings indicated that Compared with conventional surgery, CO2 laser surgery significantly reduced the recurrence rate of vocal cord leukoplakia (odds ratio [OR] = 0.25, 95% confidence interval, CI [0.12, 0.51]). CO2 laser surgery significantly improved the cure rate of vocal cord leukoplakia (OR = 3.07, 95% CI [1.17, 8.09]). Voice quality following CO2 laser surgery was significantly superior to that following conventional surgery, particularly in terms of fundamental frequency disturbance (standardized mean difference [SMD] = -0.8, 95% CI [-1.25, -0.34]) and amplitude disturbance (SMD = -0.52, 95% CI [-0.95, -0.09]). The CO2 laser group exhibited a lower incidence of postoperative adverse reactions (OR = 0.32, 95% CI [0.03, 3.19]); however, this difference was not statistically significant.
conclusionThe results of this meta-analysis suggest that CO2 laser surgery can reduce the recurrence rate of vocal cord leukoplakia, improve the cure rate, and enhance voice quality. Therefore, CO2 laser surgery is recommended as a minimally invasive surgical approach for vocal cord leukoplakia.
