Lactulose is first\u2010line therapy for HE treatment and secondary prophylaxis; however, data supporting its role in primary prevention of incident HE is less definitive. We therefore conducted a systematic review and meta\u2010analysis of the most current evidence evaluating lactulose for the prevention and treatment of HE to guide future management.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Medline, EMBASE, and Cochrane Library databases were searched for randomized controlled trials comparing lactulose to placebo or non\u2010drug control for the treatment or prevention of HE. 17 studies with 1428 patients were analyzed. Random effects meta\u2010analysis evaluated four main outcomes: overt HE (OHE), mortality, treatment discontinuation, and serious adverse events. Bayesian meta\u2010analysis assessed two main outcomes: risk of overt HE and mortality.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>We found that lactulose significantly reduces the incidence of OHE compared to no lactulose, with a pooled relative risk (RR) of 0.48 (95% CI 0.37\u20130.63) and RR of 0.43 (95% CI 0.27\u20130.69) for those focusing on primary prophylaxis. There was no increased risk of adverse events (RR 0.87, 95% CI 0.64\u20131.17). Further, using Bayesian statistics, there exists a high probability that lactulose reduces mortality in individuals with HE (pooled posterior RR 0.72\u20130.88).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Lactulose therapy safely contributes to a significant reduction in incident HE and is highly likely to reduce mortality.
