Variables listed vertically indicate model outcome variables. Variables listed horizontally indicate predictor variables. Bold font indicates significant models and variables.

a

Variable made a significant independent contribution to the model at P<0.001.

b

Variable made a significant independent contribution to the model at P < 0.05.

c

Variable made a significant independent contribution to the model at P < 0.01.

d

Logistic regression. GHQ = general health questionnaire. n/a = not applicable. OLBI = Oldenburg burnout inventory. OLBI: D = Oldenburg burnout inventory: disengagement. OLBI: E = Oldenburg burnout inventory: exhaustion. PSI = patient safety incident. QoL = quality of life. All regressions controlled for age, sex, and years in practice. Statistics represent mean standardised β coefficients for linear regressions, odds ratios for logistic regressions.
