Fig 3. Difference of hospitalization days between Group 2+3 vs. 1+4 over the 5 years.

(A) Compared to the Group 2+3, Group 1+4 showed higher hospitalization length in one year before evaluation (year −1 = 5.9±11.0 vs. 3.3±7.9 days, p = 0.02), and year 0 (7.6±15.2 vs. 2.9±19,8 days, p = 0.003). (B) Group 1+4 also had longer hospitalization stay in the subsequent 3 years (years 1 to 3 = 25.3±35.6 vs. 10.6±15.0 days, p<0.001) and total 5 years (38.7±44.4 vs. 16.7±22.4 days, p<0.001).
