Fig. 2

RCIp Z scores of neurocognitive tests. Z score means are demonstrated with a blank bar in the low inflammatory response group and striped bar in the high inflammatory response group. Error bars represent the standard error of the mean. The limit of the significant decline in performance is indicated by a continuous line at RCIp Z score of −1.96. None of the neurocognitive tests showed a significant decline at the group level. The RCIp Z scores were similar in the two inflammatory response groups, except the Stroop word task, based on the Mann-Whitney U test. Significant differences between the LIR and HIR groups are demonstrated with asterisks: ^* p < 0.05. MMSE = Mini Mental State Examination; TMA = Trail Making Test A; TMB = Trail Making Test B; DS = Digit Symbol test; Stroop W = Stroop word task; Stroop C = Stroop colour task; and Stroop CW = Stroop colour-word task
