Two factor analysis of variance (ANOVA): The two factor ANOVA showed a significant difference between Day 1 and Day 21 values of PEFR, i.e., Factor A. [F = 12.26, the F value for DF = 1, 84 at the 0.002 level (two tailed) = 11.66, hence p<0.002. Here the actual DF = 1, 84 were chosen as the nearest values in the probability table]. The difference between the 3 assessments (before, during and after) was not significant.
The t-test for paired data: The PEFR showed a significant increase after 21 days of naturopathy treatments (p<0.02). Also, there was a significant increase in the PEFR immediately after a cold chest on the Day 21. The group mean values±SD are detailed in Table 1. The symptom scores have significantly reduced following the 21 days of naturopathy treatment (p<0.05). The group mean values±SD are detailed in Table 2.
