For data

reported above the LDC, the interassay variability was <10% for all analytes measured. Statistical analyses All data analyses were conducted with SPSS, Version 17.0 (IBM Corporation, Armonk, NY) and JMP, Version 10.0 (SAS, Cary, NC). Significant P-values were ≤0.05 and P-values ≤ 0.10 were considered trends. Between-group analyses of age, education, and estimated cognitive reserve were conducted using t-tests; other demographic and clinical characteristics were categorical, so chi-square tests were used, or Fisher exact tests Inhibitors,research,lifescience,medical if cells had low frequencies (<5; Table 2). Mann–Whitney U-tests were used for between-group comparisons of neuropsychiatric symptom S3I-201 price severity (Depression-Total, Depression-Cognitive Affective Factor, Depression-Somatic Factor, Anxiety, Fatigue, Pain Severity, and Pain Interference) because questionnaire scores (except Anxiety) were not normally distributed (Table 2). Note that in Table 2 Mann–Whitney U-tests were conducted on the medians.

Inhibitors,research,lifescience,medical The percentages of immune factors ≥ the LDC were compared across Inhibitors,research,lifescience,medical groups with tests of two proportions, and the z and P-values are reported (Table 1). Between-group comparisons of plasma immune factor levels were computed with Mann–Whitney U-tests because distributions were not normal (transformations did not normalize the data), and the medians and interquartile ranges are reported (Table 1). Spearman’s rank correlations were used to assess the relationship between neuropsychiatric symptom severity and the number of immune factors that were ≥ the LDC, within the total sample and by group (Table 3). On the basis of reports in the literature (e.g., Hilsabeck et al. 2010) and on Myriad Rules Based Medicine, Inhibitors,research,lifescience,medical Inc.’s customized platform used for the analyses (i.e., Human InflammationMAP® v. 1.0), an increased inflammatory profile was defined as a greater number of factors ≥ the LDC.

[r (P-values)] Inhibitors,research,lifescience,medical between number of plasma immune factors ≥ the not LDC2 and neuropsychiatric symptom severity in adults with (HCV+) and without (HCV−) hepatitis C Regression models were developed in order to find which combination of immune factors was significantly related to neuropsychiatric symptom severity on each of the seven neuropsychiatric variables within the total sample. Some variables had values that were undetectable. For the purpose of the analysis, these undetectable values were replaced with zeros. These undetectable values should not be confused with the LDC values used for Tables 1 through ​through3.3. Models were constructed with a backward selection linear regression of 33 immune factors (14 factors were invariant and detectable in 5% or less of the samples and were eliminated from analyses; Table 1).
