Table 6. Pearson’s correlation coefficients of subscales between the Standard Chinese version of the EORTC QLQ-C30 and the Chinese version of the SF-36 among patients completed questionnaires prior to their first cycle of treatment (T1), and the second column is among patients completed questionnaires on the last day of the first cycle of treatment (T2).
