One-third of the group was free of syphilis; two-thirds showed evidence of the disease. In the syphilitic group, half were given the best treatment known at the time, but the other half, about 200 men, received no treatment at all for syphilis, PHS officials say.
As incentives to enter the program, the men were promised free transportation to and from hospitals, free hot lunches, free medicine for any disease other than syphilis and free burial after autopsies were performed.
