Table 4 shows the relative mortality of this group of patients compared with the control group. |
Collection of the control group was essential for the evaluation of seropositivity among the general female population. |
Direct evaluation cannot be done because very few ganzfeld studies have included a control group. |
A further 932 were recruited from the public to act as a control group for comparison. |
The possibly calming effect of having family present for the control group during the intervention could have played a part in the reaction. |
This study is a preliminary report of the case series without a control group for comparison. |
