Colonic poorly differentiated adenocarcinoma with abundant cancer‐associated fibroblasts diagnosed by trans‐gastric endoscopic ultrasound‐guided fine needle aspiration cytology

Abstract

They concluded that the use of the OSG method as the new diagnostic criteria for SP-LBC preparation might be a valid method to improve the precision (reproducibility) of endometrial cytology. Such a conclusion should be supported by the mentioned methodological and statistical issues. Moreover, validity (accuracy) is a completely different methodological issue and should not be confused with reliability (precision). [2][3][4][5]
