Clinical differentiation of acute appendicitis and right colonic diverticulitis: A case-control study

Figure 2 Forest plot of the logistic regression model for differentiating acute appendicitis from acute right colonic diverticulitis. ^aLonger onset-to-visit interval, right lower quadrant pain, history of diverticulitis, and high serum C-reactive protein level (>3.0 mg/dL) at the time of visit have significantly low odds ratios (ORs), which suggests that acute right colonic diverticulitis (ARCD) is more likely rather than acute appendicitis (AA) (left side of the figure). ^bNausea/vomiting and anorexia have significantly high ORs, which suggests that AA is more likely rather than ARCD (right side of the figure). AA: Acute appendicitis; ARCD: Acute right colonic diverticulitis; CRP: C-reactive protein; OR: Odds ratio; RLQ: Right lower quadrant.
