Data are presented for the RPM group and UC group, respectively. Data are presented as absolute values (per cent), mean (standard variation), or median (interquartile ranges), as appropriate. RPM, remote patient management; UC, usual care; NT-proBNP, N-terminal pro-B-type natriuretic peptide; GFR, glomerular filtration rate; COPD, chronic obstructive pulmonary disease; NYHA, New York Heart Association.
