  • 1-150 The day of admission was denoted as day 0. The day of removal was shown in parentheses. <0 means that the effusion was already present on admission.

  • 1-151 Particle agglutination test was used for all cases except for case 2 in which complement fixation test was used.

  • 1-152 Liver dysfunction, maximum alanine aminotransferase value (U/l); 210 in case 1, 2004 in case 2, 478 in case 5, 342 in case 10.

    § Time interval from the admission to the normalisation of the chest radiographs.

    # (+) = positive; (±) = indeterminate; (−) = negative.

    SIADH = syndrome of inappropriate secretion of antidiuretic hormone.
