Comparison of intra-individual coefficients of variation on the paired sampling data when inter-individual variations are different between measures

Table 2 Summary statistics of the pain intensity data for 43 patients

VAS and PV were repeatedly measured for 43 patients. The number of data records were 158
^aCalculate mean for each of 43 patients (m _subj), and calculate mean of 43 m _subj values
^bUnbiased variance, i.e. \(\sum\nolimits_{j} {{\text{SS}}_{j} } /(316 - 43)\), SS _j is a sum of squares for patient j
^cVariance of m _subj
^dSD for each of 43 patients was calculated
