3.1 Literature search
The flow chart summarizing the literature search of this meta-analysis
study is illustrated in Fig. 1. A total of 261 articles were recorded

eligibility, with 3 records were excluded for no sufficient data.
Eventually, a total of 15 eligible reports were identified for the
quantitative assessment of this meta-analysis, with 15 records
characterized single-arm analysis.
