Evidence Quality
Except for one cross-over study, where only the first step was included in our review, all included trials were case series. According to the OCEBM standards of data, all of the included experiments had a degree of proof of IV. Using the 18-criteria tool, the consistency of the proof varied from 9 to 16 points, suggesting significant variations in quality between the included tests. The articles included in meta-synthesis were 11. Furthermore, the included studies did not adequately disclose the various statistical parameters, necessitating the estimation of standard deviations. However, where experiments with imputed standard deviations for all result parameters were excluded, predictions for standard deviation imputation were found to be sufficiently robust.
