None of the clinicopathologic parameters demonstrated a significant trend towards shortened overall survival ( P > 0.05) and were not considered in the global model.

Then, as some variables may not be significant in univariate analysis but become significant in multivariate analysis, a multivariate approach was used in this study to identify jointly measurable factors that could be used to model risk of PDAC mortality.
Whilst univariate analysis returned those highly significant markers to be used as independent prognosis factors, it must not be implied that the combination of these markers would represent the best performance for the multivariate model.
