TABLE 2.

Correlation between IL-6 and other clinical information based on both test strip and ELISA results.

Correlation	CRP	Total number of days in hospital	Total number of days in ICU	Highest temperature
IL-6 (Test strip)	Rho = 0.179 (n = 43)	Rho = 0.433** (n = 36)	Rho = 0.396* (n = 35)	Rho = 0.275 (n = 35)
IL-6 (ELISA)	Rho = 0.211 (n = 43)	Rho = 0.302 (n = 36)	Rho = 0.301 (n = 35)	Rho = 0.24 (n = 35)

*The correlation is significant at the 0.05 level (two-tailed). **The correlation is significant at the 0.01 level (two-tailed).
