Total adenosine deaminase cases as an inflammatory biomarker of pleural effusion syndrome

Table 3 Laboratory analysis of adenosine deaminase, proteins, and lactate dehydrogenase in 157 cases of pleural fluids from inflammatory and non-inflammatory pleural effusion syndrome, median (25^th-75^th percentiles)/ mean ± SD¹

Non-inflammatory pleural effusion (control)	Result
Total pleural ADAa	6.85 (2.67–11.26)
Total pleural proteinb	2.64 ± 1.52
Total pleural LDH, medianc	190.5 (100.5–278.8)
Inflammatory pleural effusion (case)
Total pleural ADAa	18.4 (9.25–41.4)
Total pleural proteinb	5.05 (4.47–5.60)
Total pleural LDHc	568.5 (400.3–822.5)

¹The Shapiro–Wilk test (W) rejected the normal data from pleural total adenosine deaminase, and pleural total LDH in exudate cases (P < 0.05), but not pleural total protein in controls (P = 0.0881).

^aP < 0.0001.

^bP < 0.0001, after logarithmic transformation of data.

^cP < 0.0001.

ADA: Adenosine deaminase; LDH: Lactate dehydrogenase; IQR: Interquartile range.
