Day-time cough score improvement in subgroups of patients with cough score ≥ 3 at t0. It is shown the cough score in subgroups of children with score ≥ 3 in both treatment groups, between t0 and t4. As regards day-time cough in 14 children in the treatment group reporting a score ≥ 3 at t0, 13 (92.9%) improved, reporting a score < 3 at t4. As regards day-time cough in 13 children in the placebo group reporting a score ≥ 3 at t0, 7 (53.8%) improved reporting a score < 3 at t4. Fisher test shows a significant decrease of patients with day-time acute cough score between study product group and placebo group, at different times (day 0 and day 4) (* p = 0.03).
