Multivariate (MANOVA) and univariate (ANOVA) analyses of variance F ratios for trial x cough# effects for cough measures. Only those measures with significant P values are included

Multivariate ANOVA (MANOVA) F ratio is Wilk's Lambda approximation of F. T, task; C, cough number. Significant difference:

^*P < 0.05;

^†P < 0.01;

^‡P < 0.001.
