Medical records data were abstracted from the birth hospitalization records for mothers and focal children. Users can review the medical records abstraction form and the file documentation before applying for the contract data.
These data are available for 3,684 births (mothers and focal children). When there are no medical record data for a given case, it was for 1 of 3 reasons: (1) The hospital did not permit us to abstract records or there were too few cases for it to be financially feasible to collect data at that hospital (38%), (2) the mother refused consent (33%), or (3) the records could not be located in the hospital (29%).
The file includes hospital indicator variables but doesn't indicate the names of hospitals. Random noise has been introduced into the data to protect confidentiality. The noise should have no impact on statistical analyses.
Please note: If you are interested in working with both Candidate Genes and Medical Records files, there are some limitations. These requests are received and reviewed on a case-by-case basis, and are only for a limited set of variables from the Medical Records file, which you will need to specify in your abstract.
