Critical flicker frequency improves after alcohol detoxification and is associated with liver stiffness

Figure 3 Effect of cirrhosis status on critical flicker frequency and alcohol detoxification stratified by cirrhosis status. A: Critical flicker frequency (CFF) in patients with cirrhosis (n = 10) and without cirrhosis (n = 47) compared to controls (n = 20). Cirrhotic patients exhibit significantly lower CFF values than controls. P values were determined using Tukey’s test; B: Changes in CFF following alcohol detoxification in patients with pre- and post-detoxification measurements (n = 44). CFF was analyzed in subgroups of patients with cirrhosis (n = 6) and without cirrhosis (n = 38). CFF significantly increases in the no-cirrhosis group after alcohol detoxification. P values were determined using paired samples t-test. CFF: Critical flicker frequency. ^aP < 0.05, ^cP < 0.001.
