Howell, 200039		√			√		√		√			√		Screening army recruits is cost effective
Shafer, 199915	√				√		√					–		ICER presented. Judgment unclear
Howell, 199940		√			√		√		√			√		Age based screen cost saving
Howell, 199830			√		√		√		√			–		Age based screening most cost effective

Sellors, 199216	√					√	None		√			–		SO screening cost effective compared to NSP
Nettleman, 199117	√					√	None		√				√	Not cost effective to screen all pregnant women
Buhaug, 198918	√				√		√		√			√		Testing cost effective for women <24 yrs only
Buhaug, 198919	√				√		√		√			√		Testing cost effective for women 18–24 years only
Begley, 198935			√			√	None			√		√		Screening in FP clinics is cost effective
Skjeldestad, 198820	√					√	None		√			–		Screening for women seeking abortion
Trachtenberg, 198821	√				√		√		√			√		Screening asymptomatic women is cost effective
Phillips, 198736			√			√	√		√			√		Testing for C. trachomatis is cost effective

SO, selective opportunistic screening; SP, selective population screening; NSO, non‐selective opportunistic screening; NSP, non‐selective population screening; MOA, major outcome averted; TDM, transmission dynamic model; M, males; F, females; NAAT, nucleic acid amplification test; ICER, incremental cost effectiveness ratio; “–” implies that screening is only cost effective under certain conditions or against certain comparators.
