Within patient changes (paired data), e.g. when comparing serum levels of melatonin at baseline and after treatment, will be compared using repeated measures ANOVA or Wilcoxon signed-rank test depending on normality of data.
When comparing serum levels of CEA and IL-8 between all early stage (UICC stages I and II, n = 80) and late stage colon carcinomas (UICC stages III and IV, n = 84), the median serum level for CEA was 8.00 ng/mL in early stage and 47.97 ng/mL in late stage carcinomas (P = 0.0051).
This study compared serum levels of TNF-alpha, soluble TNF receptors 1 and 2 (sTNF-R1 and sTNF-R2), and BDNF during migraine attacks and in headache-free periods.
Objectives: The aim of the study was to compare serum levels of cytokeratin-18 of patients with bladder cancer with those of the healthy controls, and to investigate the relation between cytokeratin level and the tumor stage.
In a nested case control design, we compared serum levels between mothers of cases (n=219) and controls (n=564), selected from the Collaborative Perinatal Project, a US birth cohort study of pregnancies in 1959 1966.
The aims of this study were to compare serum levels of adipokines and expression of adipokines in peripheral blood leukocytes in patients with premature coronary artery disease (CAD), metabolic syndrome and healthy individuals.
As such, the objectives of this study were (1) to compare serum levels of IL-6, ESR, and CRP and JIL-6 level in patients who underwent primary TKA using two different types of bone cement, and (2) to evaluate the association between IL-6 levels and functional outcomes.
The aim was to compare serum levels of interleukin-6 (SIL6), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and joint fluid IL-6 (JIL-6) level between total knee arthroplasty (TKA) that used bone cement (BC group) and antibiotic-loaded bone cement (ALBC group).
In a recent study, Basak and co-workers endeavored to compare serum levels of IL-17 between healthy control and vitiligo patient groups.
To assess the potential value of serum cytokines as biomarker for asthma, or certain asthma phenotypes, or prediction of exacerbation of disease, we compared serum levels of eleven distinct asthma associated mediators of 218 families where at least two children have asthma.
