To the Editor,Thank you for your comments. The major limitations of our study were the low sample size and lack of CRP measurements in all patients because of the retrospective design of the study entitled “Relationship between platelet-to-lymphocyte ratio and coronary slow flow” by Oylumlu et al. (1) published in Anatol J Cardiol 2015;15:391-5. These may be the reasons for conflicting data with literature.
