Definition of the modified Glasgow Prognostic Score (mGPS) and sensitive mGPS (S-mGPS)

The mGPS was determined as previously described: patients with an elevated CRP (> 10.0 mg/L) level and decreased albumin (< 35.0 g/L) were assigned a score of 2, those with both elevated CRP and albumin (> 35.0 g/L) levels were allocated a score of 1 and those with a normal CRP level (< 10.0 mg/L) were given a score of 0.

As for S-mGPS in the present study, the optimal cut-off value for serum albumin was set at 45.6 g/L based on the receiver operating characteristic (ROC) curve analysis, which was in accordance with the previous report by Zhang et al. [11]. Patients with elevated CRP (> 10.0 mg/L) and decreased albumin (< 45.6 g/L) levels were allocated a score of 2, those with only one of these two abnormalities were assigned a score of 1, and those with neither of the two abnormalities were classified as having a score of 0.
