Procalcitonin and C-reactive protein as diagnostic biomarkers in COVID-19 and Non-COVID-19 sepsis patients: a comparative study

Table 6 Procalcitonin values associated with different pathogens

Bacteria	Number	PCT (IQR) (ng/mL)	Kruskal-Wallis H	P value
Staphylococcus spp.	26	0.28 (0.14–2.61)	21.959	< 0.001
Streptococcus spp.	17	2.85 (0.22–40.39)
Enterococcus spp.	6	0.29 (0.05–1.49)
Escherichia coli	46	9.43 (1.50–27.72)
Klebsiella pneumoniae	20	6.76 (1.06–23.91)
Rare pathogens	6	0.58 (0.13–35.83)

Kruskal-Wallis H test was performing to assess differences among the six subgroups. Statistically significant differences (P < 0.001) were found in the overall distribution of the data. Then, the post-hoc pairwise comparisons were conducted using Dunn’s test, which exhibited statistically significant differences between Staphylococcus spp. and Escherichia coli (H = − 3.874, P < 0.001). IQR, interquartile range; PCT, procalcitonin
