R_s is the abbreviation for Spearman’s rank correlation coefficient.
Note, the analyses presented in table 2 included participants who responded to the original or reversed version of the MTBQ at baseline.
*These analyses only included participants who had at least one GP appointment. Further, 19% of GP appointments were excluded from the analysis as a GP ID was not recorded (see methods).
