Association of recovery speed from invasive treatment and non-protein respiratory quotient. (A) Prothrombin time (PT-INR) reduction rate, which was the maximal reduction of PT-INR after treatment against the level at admission, was estimated as one of indicators for the magnitude of invasiveness and was not correlated with the non-protein respiratory quotient (npRQ) difference between days 1 and 4 (p = 0.065, r = 0.42). (B) The length of hospital stay after the nadir of PT-INR due to a treatment exhibited a significant negative correlation with the npRQ difference between days 1 and 4 after normalization by PT-INR reduction rate (p = 0.0002, r = −0.73). (C) The length of hospital stay after the nadir of PT-INR was 175 ± 76 days and 40 ± 59 days in npRQ-deteriorated and npRQ-improved cases after admission, respectively, and significantly different each other (p = 0.0006).
