  • a The table presents the results of the pathway analysis of NK cell transcripts derived from 6 HIV- and 8 HCV-infected patients. The significance of modulation, not necessarily up- or downregulation, of each pathway is indicated by the P value. The z-score displays the overall direction, and the degree of overlap with the preset gene lists per pathway is indicated by a ratio. The HBV-infected cohort, regardless of the clinical phase, did not significantly modulate (according to preset criteria of P < 10−4 and minimal overlap of 5%) a single known pathway and was therefore not included in this table.homologous end joining; NA, not applicable.

  • b Only pathways with a ratio of >0.05 and P value of <10−4 are depicted, resulting in the exclusion of HBV-infected cohorts.
