Multivariable linear regression for impact of respondent group and age on disease perception composite score

Covariates	Estimated coefficient (difference on 80-point scale)*	95% CI	P value
Age (per 10-year increment)	−0.37	−0.68 to 0.05	0.02
Respondent group (all in comparison to laypeople)
Members of parliament	1.71	−1.53 to 4.94	0.30
Nurses	4.12	3.14 to 5.10	<0.001
Non-psychiatrist physicians	5.70	4.60 to 6.80	<0.001
Psychiatrists	10.53	7.66 to 13.41	<0.001

*Per one unit increase in the covariates included in the model (eg, per 10-year increase in age), the estimated coefficient can be interpreted as the disease score change associated with the covariate. For instance, per 10-year increase in age (first covariate listed in the table), there is an average 0.37 decrease in disease score.
