CRP and atrial fibrillation: In investigating the predicting factor for ICU admission among splenic infarction patients, the univariate logistic analysis yielded five variables with a p-value of less than 0.1: tachypnea (p = 0.019), a past history of diabetes mellitus (p = 0.09), a past history of atrial fibrillation (p = 0.09), a positive qSOFA score (p = 0.026), and CRP elevation (p = 0.011).
