From: Association of DRD4 uVNTR and TP53 codon 72 polymorphisms with schizophrenia: a case-control study
Structural equation modelling of inter-relationships among variables with respect to schizophrenia. p53CC: dummy variable where 1 refers to the CC genotype of the TP53 codon 72 polymorphism and 0 refers to the other possible genotypes; DRD4c: dummy variable where 1 refers to the long form allelic variants of the DRD4 uVNTR polymorphism (≥ 5 repeats) and 0 refers to the short form allelic variants (≤ 4 repeats); AGFI: adjusted goodness-of-fit index. The numbers are the coefficients of correlation between two variables.
