Data are presented as median (interquartile range), unless otherwise indicated. NA: not available; POA: port of arrival; CPA: community post-arrival screening (by invitation); RC: reception/holding centre; OS: occasional screening. #: reports on screening of a specific group of refugees at or shortly after arrival; these studies were also considered occasional screening studies since they covered only a specific group of migrants; ¶: data from one UK study, coverage of entry screening for the Netherlands is estimated to be ∼70% 41.
