dc.description.abstract | The study presented below aimed to compare survival of colorectal
cancer patients against survival of a sub-population with a secondary disease,
in
ammatory bowel disease (IBD).
The data were taken from a observational study, that is there was no explicit
design. The study had many complications, but the most signi cant aspect was
that the number of controls was much greater than the number of cases of interest.
Some techniques are used to overcome these obstacles, including: matching of the
dataset, to make the controls and cases as similar as possible at time of diagnosis,
e ectively retrospectively tting a design; weighting of the data, using both the
propensity score and the number of similar patients found in matching. | en_US |
