# Sample sizes for each variable indicated, with unknown cases not included in individual analyses

##Comparisons provided for differences between the 3 diagnostic groups (column 2) and for comparison Group1 and Group2(columns 3 and 4). Significance: * p < .05, ** p < .01, *** p < .001. Odds Ratios (confidence interval) provide the strength and direction of the relationship, indicating the liklihood of subjects with schizophrenia being more (>1) or less likely (<1) than those with other psychiatric disorders (Column3) or those with no identified disorder (Column 4) to exhibit the charactristic under consideration (ie having never married, living with parents, or not being in employment).
