Preferred Label : Baseline Characteristics;
NCIt definition : Subject data gathered prior to an event or intervention, which may include medical
history, demographic, and clinical data.;
Alternative definition : CDISC-GLOSS: Demographic, clinical, and other data collected for each participant
at the beginning of the trial before the intervention is administered. NOTE: Randomized,
controlled trials aim to compare groups of participants that differ only with respect
to the intervention (treatment). although proper random assignment prevents selection
bias, it does not guarantee that the groups are equivalent at baseline. any differences
in baseline characteristics are, however, the result of chance rather than bias. The
study groups should be compared at baseline for important demographic and clinical
characteristics. Baseline data may be especially valuable when the outcome measure
can also be measured at the start of the trial. [CONSORT statement];
