Fig.7 Comparison of forest plot of SCr level between CRRT and control groups. (a)The SCr level of two groups was less than 95. (b)The SCr level of control groups was greater than 100.
3.4.6Serum potassium level
Six studies reported changes in serum potassium, but the results showed no statistically significant difference between the two groups.(WMD=-0.00, 95%CI-0.31 to 0.31, I2=89%,P=1.00)(Fig.8)
