“…The stage system used to perform the biopsy in most studies was the Kleiner and Brunt system in 55% of the studies (19, 20, 22, 24, 26, 27, 31, 32, 35, 39, 42, 44-50, 52, 53, 56, 58-63, 65, 68, 70, 75, 76, 81-84, 86, 91, 94-100, 106, 107, 113, 114, 117, 119-124, 126, 128, 130-136, 138, 140-144, 149-153). Regarding the severity of fibrosis, AF was the most diagnosed, with 182 studies (20-26, 28, 29, 32, 33, 35, 37, 38, 40, 44, 48, 49, 52, 54-56, 58, 66, 67, 71-75, 77-80, 83-86, 89-91, 94, 97-101, 104-107, 109, 110, 112-115, 118, 127-134, 136, 137, 140, 141, 143-154), followed by SF, with 140 studies (22-25, 30, 35, 36, 38, 41, 42, 47-49, 51, 52, 54, 55, 58, 61, 71, 73, 74, 76, 77, 81-84, 86, 90, 95, 98-101, 105-107, 110, 113, 115, 116, 119, 121, 124, 127, 129, 131, 134-136, 138, 144, 147, 150-152), then by any type of liver fibrosis (107, 112, 114, 120-122, 124, 126, 132, 138, 140-143, 149-151, 153, 154) and cirrhosis (8,18,19,22,26,40,47,52,92,105,111,113,116,119,128,131,154) in 18 and 16 studies, respectively (Supplementary Text S2 and Supplementary Tables S2, S3). The serological biomarker cutoff values for each severity level have been described in more detail in (Supplementary Table S4).…”
