  • Analyses were based on 152 cases with no missing data. Model 1 (χ 102 = 34.46; P = .00016) includes all variables assessed in univariate analysis; model 2 (χ 92 = 33.95; P = .00009) includes only those variables with P ≤ .10 in univariate analysis; model 3 (χ 52 = 31.002; P = .00001) includes only those variables with P ≤ .10 in multivariable analysis
