Model 1 using full range of consultation duration times, Model 2 restricted to consultation duration times of over 3 min; Model 3 restricted to separate consultations only

a

Regression coefficients were converted into per cent change in consultation duration times using the formula [exp(β)−1]×100

b

‘Adult’ indicates an individual going to the consultation alone, and ‘adult with child’ indicates an individual going to the consultation with a child
