Addressing sickness absence among adolescents and young adults: an evaluation of the Medical Advice for Sick-reported Students intervention

Table 4 The association of study condition with primary outcome measures

Primary outcomes	Crude model^a	Adjusted model^b
	Intervention vs control condition	Intervention vs control condition
	B (95% CI)	B (95% CI)
Days of sickness absence in past 8 weeks	-0.71 (−1.77;0.35)	-1.13 (-2.22;-0.05)
	OR (95% CI)	OR (95% CI)
Education fit (yes/a bit)^c	4.37 (1.25; 15.25)	3.61 (0.98;13.31)
School performance (very good/good)^d	1.81 (0.81; 4.07)	1.77 (0.78; 4.03)

Note: bold numbers indicate statistical significance (p < 0.05) between the intervention condition and the control condition, calculated using linear or logistic regression models with the control condition as reference
^aModel of follow-up score with correction for corresponding baseline score, without correction for confounders
^bModel of follow-up score with correction for corresponding baseline score, intermediate vocational education level and gender
^cMeasured on a 5-point Likert scale, dichotomized into ‘yes’ (i.e. ‘yes’ and ‘a bit’) and ‘no’ (i.e. ‘I do not know-no’)
^dMeasured on a 5-point Likert scale, dichotomized into ‘good’ (i.e. ‘very good’ and ‘good’) and ‘not good’ (i.e. ‘average and less’)
Missings: Baseline days of sickness absence in past eight weeks = 8, follow-up days of sickness absence in past eight weeks = 20; baseline education fit = 9, follow-up education fit = 23; Baseline school performance = 8, follow-up school performance = 23; intermediate vocational education level = 8; gender = 0
