Population characteristics according to recruitment source.

Abstract:

:Considerable variability was observed among recruitment sources and centers in the proportion of first protocol visits proceeding to entry. Some of the reasons for these differences are explored. Several characteristics of the participants were also analyzed to determine whether significant variability existed among recruitment sources. The variability encountered suggests that these characteristics might be exploited in selecting recruitment sources for clinical trials.

  • Research related to medical treatment of cardiovascular disease.

    abstract::Medical treatment of heart disease has improved significantly in the past 30 years. The spectacular change in the natural history of rheumatic heart disease is apparent from a 1948 article that reported that 42% of children with rheumatic heart disease died of rheumatic infection or bacterial endocarditis.
