Table 4: 20 Session Group - Null Hypothesis

Response 20 Sessions Group NBD Remission 39 25.5 Not remission* 12 25.5

*Not-remission = (Partial remission + Negative responses) Chi-Square = 7.6 p < 0.01 @ df 1: Remission rate statistically significant : Null hypothesis - If procedure has no effect the frequency of Remission vs Not-Remission would be the same
NBD ( Normal Binomial Distribution)

Table 5: 10 Sessions Group - Null Hypothesis

Response 20 Sessions Group NBD Remission 39 45.5 Not remission* 52 45.5

*Not-Remission = ( Partial Remission + Negative response)    Chi-Square = 0.93 p > 0.3 @ df 1
Remission rate not statistically significant from Not-Remission rate Null hypothesis - If procedure has no effect the frequency of Remission vs Not-remission would be the same. NBD ( Normal Binomial Distribution)

Figure 1 illustrates the percentage of cases that achieved remission and partial remission with course of VAX-D therapy. 91 patients received on average 9 daily sessions(10 Sessions group). 51 patients received on average 18 daily sessions (20 Sessions group). Patients that failed to respond were classed as a negative response. Statistical analysis revealed:

Remission 20 Sessions vs 10 Sessions p <.01    20 Sessions group Remission vs Negative p <.01
10 Sessions group Remission vs Negative p >.05
