We listed the literature reference, the author, a concise summary describing the study cohort and an age reference. Mean age was used if available, otherwise we depicted the study cohort’s age range. Kappa values shown for HYP, DM, MI, HF, KD, CB)/COPD, RA, arthrosis.
*Highest reported kappa values for each disease were used, as they may vary due to different disease-definitions within a study.
