Significant improvement in ‘being self-conscious around people’ was observed from day 1 (p < 0.0001). The social activity category score and the individual factor of ‘interacting with others’ score significantly improved from day 1 (p < 0.0001) (Table 9). The time to resolution was day 3 for ‘being self-conscious around people’ and the median time to resolution for the ‘interact with others’ factor was day 4 (Figure 4). At last dose, social activity and both individual factors improved by at least by 70% (Table 9). Finally, the individual factor of ‘interacting with others’ showed a positive correlation with relief of nasal congestion (‘plugged nose’ symptom) (r = 0.60; p < 0.0001) (Table 12).
