Model 1: Unadjusted logistical regression on hypothesised correlated variables; Model 2:Logistical regression, adjusted for demographic covariates (Age, Gender & SEIFA) and condition; Model 3: Logistical regression, further adjusted for environmental covariates (TV in room & Computer/EGD in bedroom)
OR – odds ratio; CI – confidence interval; *p<0.05; **p<0.01;
