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.
