3.1 Literature search and screening results
The literature search spanned from September 1, 2000, to September 1, 2023, and the literature search and screening were completed according to the systematic article collection flowchart (Figure 1), with a total of 1,072 retrieved studies, including 13 duplicate articles. By reading the titles and reviews, 996 irrelevant articles were excluded. Of the 63 articles, two had unavailable full text, and 61 papers in total were ultimately included. 38 of the 61 papers were excluded for a variety of reasons: 22 studies did not specify the recovery of vertigo, and 12 researches failed to satisfy the criteria for inclusion because of improvements and outcome indicators. One study included pregnant women, and 3 studies had missing data. A total of 23 studies and 4290 patients were selected for the meta-analysis[3,4,6-8,11-28].
