Chest x-rays: What to look for:

Two findings are associated with mortality: bilateral pleural effusions and multilobar disease.The kappa agreement for detection of these findings is modest (.46 and .51 respectively). The relative risk of bilateral pleural effusions as a predictor of mortality was 2.8 and the odds ratio of multilobar disease as a prognostic factor for mortality was 3.1
