question: Compared to baseline what was the result of receive lactulose (30–60 mL/day) + probiotic (200 million colony forming units of seven bacteria species/day) (Gp-LPr) or probiotic alone (Gp-Pr) or lactulose + placebo (Gp-L) on psychometric hepatic encephalopathy score (PHES)?
context: After 8 weeks follow-up, there was a deterioration in the Gp-L (−1.6 ± 2.9 to −4.8 ± 4.2), while the status of the Gp-LPr and Gp-Pr arms did not change significantly [Figure 2].
