Furthermore, based on previous data regarding the role of Fusobacterium nucleatum (Fn) in cancer and inflammation-related dysbiosis [28,29], the researchers conducted a PCR search for Fn genetic material and showed that 87.5% of the AL patients were positive for Fn, which was also an independent risk factor of AL (OR 22.308, AUC 71.94%, p = 0.048). The gene discussed is FN1; the disease is axial length measurement.
