Drs. Mindlin and Lobach have raised interesting points in their letter. In our paper we described respondents' perceptions, corroborated by some independently obtained data about the ease of consulting the physician identified as the one from whom care is said to be usually sought. It was our aim to show how these perceptions of regular source of care vary with type of physician. The study dealt with children of all ages and socio-economic class in an entire metropolitan area.
