4 META-ANALYSIS
The statistical analysis of the data will be performed by an external collaborating professional and interpreted by the main researcher. For data analysis, a database will be built on a Microsoft Excel spreadsheet that will be exported to the Minitab 18® statistical program (version 18, Minitab, LLC, State College, Pennsylvania, USA) (Minitab®) and also to OriginPro® 9 (DPR Group, Inc., Northampton, Massachusetts, USA) (Moberly, Bernards, Waynant, 2018). Common descriptive statistical analysis will be performed, obtaining the values ​​of total N, mean, standard deviation, confidence interval (CI), and percentage (frequency) for all predictors. The One-Way test (ANOVA) will be applied, adopting the α level less than 0.05 with a statistically significant difference for the 95% CI. The value of R-sq (I2) will be analyzed to discover the inaccuracy or heterogeneity of the analyzes. The S factor will indicate the standard deviation between the data points and the adjusted values.
