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].
