Augmentation of venous drainage with either kinetic-assisted drainage (KAVD) or vacuum-assisted (VAVD) has been used clinically in order to overcome added venous resistance due to smaller venous cannulae or tubing. This in-vitro study evaluates the extent of hemolysis and sub-lethal red blood cell membrane damage than occurs with augmented (kinetic or vacuum) when compared to conventional gravi...

We present a critical analysis of the generalized use of the "impact factor". By means of the Kruskal-Wallis test, it was shown that it is not possible to compare distinct disciplines using the impact factor without adjustments. After assigning the median journal the value of one (1.000), the impact factor value for each journal was calculated by the rule of three. The adjusted values were homo...

χ value in the Chi-square distribution used to test for significant differences between three (or more) independent groups when using the Kruskall-Wallis non-parametric analysis of variance where the dependent variable is measured on an ordinal scale. p probability of making a type I decision error. z a value in the standard normal distribution that may be related directly to a probability valu...

OBJECTIVES To compare third-party payor reimbursement for patients evaluated in a university-based pediatric weight management clinic in central Kentucky. STUDY DESIGN Demographic and reimbursement data were reviewed for 120 patients evaluated January to December 2004. Statistical analysis included Kruskal-Wallis test and Friedman's test. RESULTS Overall, median reimbursement was 60%. For n...

PURPOSE To compare the effects of the antidepressant drugs duloxetine and amitriptyline on depressive behaviors in rats. METHODS Fifteen male Wistar rats were given systemic injections of duloxetine, amitriptyline or saline prior to a Forced Swimming Test (FST). Immobility and number of stops were measured. Data were analyzed by one-way ANOVA and Kruskall-Wallis. RESULTS Rats given injectio...

Three protein peaks were identified in the serum of men with prostate cancer and BPH, but not in controls, with relative molecular masses of 15.2, 15.9 and 17.5 kDa. These three proteins were significantly associated with BPH and prostate cancer when compared with controls ( P = 0.001, 0.004, and 0.011, respectively, Kruskal–Wallis test). Interestingly, the 17.5 kDa protein was more abundant in...

INTRODUCTION Prenatal screening and diagnosis is important for the detection of birth defects and genetic diseases. The nationwide proficiency testing (PT) of maternal serum prenatal screening in second trimester in China has been launched since 2003 and partly reflected the performance of screening laboratories. This study analysed the 2015 PT results to examine the performance of clinical lab...

The two-sample Lepage test, devised for testing equality of the location and scale parameters against the alternative that at least for one of the parameters the equality does not hold, is extended to the general case of k > 1 sampled populations. It is shown that its limiting distribution is the chi-square distribution with 2(k — 1) degrees of freedom. This fc-sample statistic is shown to yiel...

Abstract. This paper studies the effect of deviating from the normal distribution assumption when considering the power of two many-sample location test procedures: ANOVA (parametric) and Kruskal-Wallis (non-parametric). Power functions for these tests under various conditions are produced using simulation, where the simulated data are produced using MacGillivray and Cannon’s [10] recently sugg...

Methods 31 HIV seropositive antiretroviral therapy naïve and 8 HIV uninfected healthy control subjects were recruited and characterized as being early, late or slow progressor. Peripheral blood mononuclear cells were isolated from each study subject and stimulated with HIV-1 subtype ‘C’ gag peptide pool and assessed for IL-17 cytokine producing CD4-T cells using intracellular cytokine staining....
