multivariate analysis of the data showed that dr type ( p = .2488 ) and presence of ia ( p = .1604 ) had no effect on serum c-peptide over time , but sex ( p = .0146 ) , age at onset ( p = .0002 ) , and presence of ica ( p = .0147 ) significantly contributed to the variation of serum c-peptide over time .
