Effects of Four Types of Watermelon Frost Combination Medications for the Treatment of Oral Ulcers: A Network Meta-Analysis

Abstract

Objective. The aim of this study is to identify the effectiveness of the four different watermelon frost combination medications in the treatment of oral ulcers through network meta-analysis and rank them based on their performances. Methods. Five randomized controlled studies of four distinct types of a combination medication for the treatment of oral ulcers were observed in numerous databases, and a network meta-analysis was conducted to evaluate the odds ratio (OR) and sequence of the diverse treatments using Stata software (version 13.0). The underlined studies were categorized into two groups: the control group (watermelon frost alone) and the observation group (one of four watermelon frost combinations). Results. The study comprised of 598 cases and the findings indicated that the pooled OR and 95% CI of oral ulcers that improved relative to watermelon frost alone were 3.26 (1.28 to 8.30) for watermelon frost and Kangfuxin fluid, 8.74 (2.94 to 26.02) for watermelon frost and erythromycin, 6.53 (1.81 to 23.50) for watermelon frost and metronidazole, and 2.62 (0.63 to 10.95) for watermelon frost and cydiodine buccal tablets. The study showed the significant efficacy of watermelon frost combination medications. In terms of clinical efficacy, the combination of watermelon frost and erythromycin was the most promising concomitant medication. It had an 86.3 surface under cumulative ranking (SUCRA). Conclusion. All the studied watermelon frost combinations were effective against oral ulcers validating the use of watermelon frost for oral ulcers. The combination of watermelon frost and erythromycin is the most promising candidate among the four combinations for the treatment of oral ulcers.
