Figure 1

Box plots showing serum YKL-40 (YKL-40s) levels (A1), pleural YKL-40 levels (YKL-40p) (A2) and the ratio of pleural YKL-40 and serum YKL-40 levels (A3) among the subjects with congestive heart failure (CHF), tuberculous pleural effusions (TBPE), parapneumonic effusions (PPE), and malignant pleural effusions (MPE). Similarly, B1, B2 and B3 show the box plots of YKL-40s, YKL-40p and the ratio of YKL-40p/YKL-40s among transudates and exudates, respectively. The box plots show the minimum value, the 25th, 50th and 75th percentiles, and the maximum value. Specific data are detailed in Tables 2,3.
