Table 4.

Duration of hospital and ICU length of stay according to increasing p16 levels in PBTLs

*Univariate analysis, HR (95% CI) **Multivariable analysis, HR (95% CI)
Duration of stay in the hospital 1.07 (0.87-1.32) 1.10 (0.87-1.40)
Duration of stay in ICU 1.13 (0.90-1.43) 0.98 (0.74-1.28)
*

Cox proportional hazards regression was performed, with results reported as HR (95% CI) of discharge from the hospital or ICU

**

Adjustments were made for chronologic age, frailty status and Charlson comorbidity index

Abbreviations: HR, Hazard Ratio; CI, Confidence Interval; ICU, Intensive Care Unit
