‘Univariable’ denotes single factor χ2 test for each predictor. ‘Multivariable’ denotes binomial logistic regression result for each predictor with all other predictors in the model. Cases are excluded where one or more predictors were missing, which reduced the sample size from 37 229 to 30 541.
↵a The univariable analysis here refers to the prospects variable with three levels: agree, neither, disagree. df = degrees of freedom.
