a Estimated from ANCOVA model with factors for treatment and centre and a covariate for baseline throat soreness.
b A negative difference favours the first treatment against second treatment.
** Significantly different compared with the unflavoured, non-medicated lozenge at the 1% level.
*** Significantly different compared with the unflavoured, non-medicated lozenge at the 0.1% level.
CI, confidence interval; LS, least-squares; SD, standard deviation; ITT, intention-to-treat; PP, per-protocol.
Throat soreness measured on an 11-point scale where 0 = Not sore, 10 = Very sore
