Three homogenous studies reporting procalcitonin documented a highly significant value ( p < 0.00001) with a I 2 value of 57% and odd ratio of 5.77 (95%CI: 3.35, 9.95) beyond the cut off value of 0.1 ng/mL [ Figure 6b ].[ 14 , 15 , 20 ] Investigation of heterogeneity Heterogeneity was found in all the comparisons with I 2 value ranging from 56% to 99% [ Table 3 ].
