Dear Editor,
As a reply to the Letter to the Editor written by Yasin Alper Yildiz (1), first we are thankful for the interest in our study.
We thank the authors for their careful reading of our manuscript and for raising this important methodological issue. We agree that the equations used for the calculation of predicted morbidity and mortality should have been stated more explicitly in the Methods section.
For clarification, the physiological score (PS) and operative severity score (OS) were calculated according to the original POSSUM scoring system. [read more]
