The total asthma symptom scores by study day. The plot includes 1 standard deviation error bars (limited on the lower bound to a value of 0.0 so as to avoid negative values) and notes the sample size (N,) mean, and SD of each time point. Of importance, Days 15, 16, and 17 (the allowable window of 3 days beyond Visit 2) includes a small number of observations at N = 14, 3, and 2, respectively (denoted by separate boxed area in the plot). In general, asthma symptom scores decrease from Days 1–15. Due to low N, the estimates for Days 16 and 17 do not provide confidence in any trend
