OB-43
Initial Prenatal Examination
Form OB-43 was used to record results of the initial physical examination
following selection of the pati~nt into the project sample. First used as a
pretest form in July 1961, the form was implemented into the study in April of
1962; form OB-43 replaced pages 3 and 4 of form OB-9, where information on the
initial pelvic examination and general examination had been recorded. Page 2
only was revised in October 1962. Data records generated by form OB-43 were
punched on cards 1343 and 2343 of the master file (Table OB-43.1).
