Purpose: To date, the optimal treatment for portal vein thrombosis (PVT) in cirrhotic patients has not been established in guidelines or consensus. We conducted a systematic review and meta-analysis to evaluate the effect of anticoagulation therapy in patients with cirrhosis and PVT.
Methods: PubMed, Embase, the Cochrane Central Register of Controlled Trials, and ClinicalTrials.
Purpose: To examine the prevalence of refractive error and some associated factors in Chinese preschool children.
Methods: The Jinshan District Eye Study was a school-based survey of eye health in a large sample of 4- to 6-year-olds attending kindergartens from May 2013 to December 2013 in Shanghai. Refractive error was measured using an autorefractor under noncycloplegic conditions.
