![Comparison of median Ct values in severe acute respiratory syndrome coronavirus 2 wild-type and B.1.1.7 lineage by symptom duration, Berlin, Germany, January–March 2021. A) Symptom duration <7 days. B) Symptom duration >7 days. The boxplots indicate medians (center) and 25th (top) and 75th (bottom) percentiles (i.e., quartile [Q] 1 and Q3). The upper whiskers reach the largest value with a maximum Q3 +1.5 interquartile range. The lower whiskers reach the smallest value with a minimum Q1 –1.5 interquartile range. The numbers on top of the boxplots indicate the total number of observations included in the comparison. Ct, cycle threshold.](/eid/images/21-0845-F2.jpg "Figure 2.
