“…Over 100 epidemiological studies have been identified in the primary search specifically mentioning F. nucleatum in the abstract. Supplementary Table 10 summarizes the characteristics and main outcomes of 42 of these epidemiological studies which met the eligibility criteria, most of which comparing F. nucleatum presence/abundance in feces from CRC patients versus healthy controls and of tumor tissue versus adjacent normal tissue ( Supplementary Table 10 ; Castellarin et al, 2012 ; Flanagan et al, 2014 ; Fukugaiti et al, 2015 ; Ito et al, 2015 ; Mira-Pascual et al, 2015 ; Wang et al, 2016 ; Xie and Fang, 2016 ; Yu et al, 2016 , 2017 ; Amitay et al, 2017 ; Drewes et al, 2017 ; Eklöf et al, 2017 ; Liang et al, 2017 , 2021 ; Scott et al, 2017 ; Suehiro et al, 2017 ; Yamamura et al, 2017 ; Yoon et al, 2017 ; Hale et al, 2018 ; Hsieh et al, 2018 ; Kwong et al, 2018 ; Repass, 2018 ; Russo et al, 2018 ; Tsuchiya et al, 2018 ; Bundgaard-Nielsen et al, 2019 ; Butt et al, 2019 ; Chen et al, 2019 ; De Carvalho et al, 2019 ; Kageyama et al, 2019 ; Saito et al, 2019 ; Tunsjø et al, 2019 ; Yachida et al, 2019 ; Zhang et al, 2019 ; Alkharaan et al, 2020 ; Boehm et al, 2020 ; Gantuya et al, 2020 ; Kashani et al, 2020 ; Reynolds et al, 2020 ; Eisele et al, 2021 ; Kawasaki et al, 2021 ; Kurt and Yumuk, 2021 ; Pignatelli et al, 2021 ). Two meta-analyses published in 2020 reported pooled ORs of 8.3 for detection of F. nucleatum in colorectal specimens (feces/mucosa/tissue) and being diagnosed with CRC, and 10.06 for detection of F. nucleatum in CRC tissue versus healthy tissue from controls ( Supplementary Table 7 ; Gethi...…”
