Unadjusted and adjusted OR for periprocedural myocardial injury according to quartiles of HbA1c.

HbA1c  = glycated hemoglobin; cTnI  =  cardiac troponin I; OR  =  odds ratio; ULN  =  upper limit of normal; MI  =  myocardial infarcton; NT-proBNP  =  N-terminal pro-brain natriuretic peptide.

HbA1c即糖化血红蛋白（glycated hemoglobin）；cTnI即心肌肌钙蛋白I（cardiac troponin I）；OR即比值比（odds ratio）；ULN即正常上限（upper limit of normal）；MI即心肌梗死（myocardial infarction，原文拼写为infarcton，系笔误）；NT-proBNP即N末端B型利钠肽原（N-terminal pro-brain natriuretic peptide）。
