Trend analysis for the ratio of OLAB/oxLDL and TIMI risk score at different time points after acute myocardial infarction.

The OLAB/oxLDL ratio associated with each TIMI risk score was presented as a median value (interquartile range; i.e., 25th–75th percentile). The Jonckheere-Terpstra test for trend was performed and p values were indicated.The TIMI risk score was calculated as the weighted sum of several clinical predictors, including age ≥75 years (3 points); age 65 to 74 (2 points); history of angina, diabetes, or hypertension (1 point); Killip class II to IV (2 points); heart rate >100 beat/min at the time of presentation (2 points); systolic blood pressure 4 hours from symptom onset (1 point); and weight
