Table 1.
Description of findings for 74 horses with pleuropneumonia and pleural fluid at or above the point of the shoulder. Cases were subdivided into 2 groups based on the deposition of fibrin in the pleural space at any time during hospitalization. Data are expressed as number of horses (percent of the group) for dichotomous variables or median (IQR) for continuous data. Significant P‐values are in bold. PF, pleural fluid; DPOS, dorsal to the point of the shoulder
