Briefly, for each patient, we collected: date of birth, gender, primary tumor, date of diagnosis, anti-neoplastic therapy, type and setting of anti-neoplastic therapy (adjuvant/neoadjuvant or advanced), treatment start and end date, date of last cycle and date of contrast-enhanced CT scan.
All collected dates with homogenous brown color were further dried by exposing them to open air for two weeks before further processing.
We collected data on date of birth, cardiovascular disease history and established risk factors for cardiovascular diseases using questionnaires.
At the initial visit with the SARS case-patients, we collected data on demographics, date of illness onset, clinical symptoms, and exposure history.
In addition, vaccination status was self-reported and could not be validated against official records, and we did not collect dates that antiviral drugs were used from each person.
Next, because this is a cross-sectional analysis and we did not collect dates for the sexual behaviour data (beyond knowing they occurred in the 12 months before the interview), we cannot determine the exact timing of sexual risk behaviour with respect to viral suppression.
We collected relevant dates based on the detailed approach described by Andersen, Cacioppo and Roberts [ 18].
We collected the dates of filled prescriptions, daily dose, number of days supplied, and the number of pills per prescription.
We collected data on age, sex, date reported, and country of infection and used social security numbers for identification.
We compiled a yearly timeline of Sd1 from 1940 to 2002 by country for the literature review (we collected the date of the events, and date of publication) and from 1990 to 2002 for the travellers comparison.
