question:
In 2000, Swedish researchers conducted a study to see if cannabis use increased the risk of schizophrenia. To this end, they identified 50,087 men who were part of the compulsory military recruitment between 1969 and 1970. As part of the recruitment process, they were interviewed where, in a non-anonymous way, they indicated the use of cannabis. This group was followed from 1970 to 1996 through the hospital records to find out how many of them had a diagnosis of schizophrenia registered during that period. For the analysis, they divided the subjects into two groups those who indicated that they had used cannabis 2 or more times and those who used cannabis less than 2 times and calculated the frequency of schizophrenia in each of them. What kind of epidemiological study is it about?
