  1. * p < 0.001; xUnspecified p value; – parameter was not reported; ρc: concordance correlation coefficient. The MAE results from [26] are calculated in this work to obtain a mean value of the individual results. Refer to “PRV and statistical analysis” section for parameter definitions. Refer to Table 1 for the conditions/method of the study. (Note: the results reported in [22] appear to make no sense, likely, due to a transcription error. Even so, the results are included in this table)
