backpain | R Documentation |
These data are from a 1:1 matched case control study to investigate the risk of driving on lower back pain caused by acute herniated lumbar intervertebral discs. A total of 217 cases were individuals between the ages of 20 and 64 living in New Haven, Connecticut. For each case a control was selected from patients admitted to the same hospital as the case, and matched with the case based on sex and age (within 10 years).
