Mean values with different superscript letters were significantly different (P < 0.05).

1

GLM test was used for all variables except for gender for which a chi-square was used and for the number of consultations for which median values were compared using the non-parametric Kruskal–Wallis test.

2

GLM tests were adjusted for age, gender, year of recruitment, and BMI level at inclusion, except for the BMI at the inclusion which was adjusted for age, gender, and year of recruitment.

3

Median values.

F: failure group; SM: successful maintenance group; UM: unsuccessful maintenance group.
