Table 5 Categorized risk groups for advanced fibrosis according to combined FIB4 index and NAFLD fibrosis score (NFS).

From: Validation of the FIB4 index in a Japanese nonalcoholic fatty liver disease population

   FIB4 index (cut-off values proposed by Sterling et al.) Total
  Low cut-off point (< 1.45) Indeterminate (1.45-3.25) High cut-off point (> 3.25)  
NFS Low cut-off point (<-1.455) 283 [1 (0.4%)] a 42 [4 (9.5%)] a 3 [0 (0.0%)] a 328 (56.9%) [5 (1.5%)]
  Indeterminate (-1.455-0.676) 53 [5 (9.4%)] a 122 [19 (15.6%)] b 31 [14 (45.2%)] c 206 (35.8%) [38 (18.4%)]
  High cut-off point (> 0.676) 0 17 [4 (23.5%)] b 25 [17 (68.0%)] c 42 (7.3%) [21 (50.0%)]
Total 336 (58.3%) [6 (1.7%)] 181 (31.4%) [27 (14.9%)] 59 (10.2%) [31 (52.5%)} 576 (100%) [64 (11.1%)]
  1. Total number of patients [stage 3-4 (%)]
  2. Patients were categorized into three groups, "low-risk" (< 10%) a, "intermediate-risk" (10-30%) b and "high-risk" (> 30%) c, based on the combination of FIB4 index and NFS.
