Stability index of the trends generated by the two methods are reported with median values and IQR. Whole period refers to the first 7 days from the beginning of the recording. A lower value of the index means higher stability. See Fig. 4 for statistical comparisons. CPPopt: algorithm resulted after the fine-tuning process. CPPopt_MA: previously available algorithm
