Two-year QALY kinetics in ABRP, non-ABRP and “no-infection” groups in our 351 patients overall. Bars and vertical lines indicate mean QALY values and standard errors, respectively. QALY kinetics is indicated by the corresponding mean regression line for ABRP group (black line), non-ABRP group (gray line) and “no-infection” group (white line). The ABRP group displays the worse progress in QALY kinetics over time (lower slope of its corresponding mean regression line) compared to the two other groups. QALY, quality-adjusted life years; SE, standard error; ABRP, antibiotic resistant pathogen; Intercept of the regression line, the QALY value where the regression line crosses the y-axis at the theoretical day, 0; Slope of the regression line, the rate at which QALY values change between two-consequent follow-up examinations. *P < 0.001; †P < 0.05
