Jurek AM et al. – The authors did not detect other case–control differences in recall (differentiality), even though the average time between childbirth and interview was 2.7 years for case and 3.7 years for control mothers. Many conditions exhibited notable differences between interview and records. They recommend use of multiple measurement sources to allow both cross–checking and synthesis of results into more accurate measures.
