  1. Prevalence of the sonographic findings by the reviewer. Data are presented in number and percentage. Total number of ultrasound examinations were 590. Each scan could include more than one finding, e.g. left-sided pleural effusion recognised in left lateral zone and a single B-line in right anterior zone
