The data comprise two groups or treatments, namely with and without the novel supplement added,...
Significant differences in measured values were evaluated with an analysis of variance using Fisher's t-test and paired or unpaired Student's t-test, as appropriate. Statistical significance was set at o0.05. RESULTS Binding of irbesartan and losartan to WT and mutant AT1 receptors The Kd of ...
Unpaired 2 Sample T-Test:-The test is performed to compare the two means of two independent samples. These samples came from the normal populations having the same or unknown variances. Paired 2 Sample T-Test:-In the case of paired data of observations from a single sample, the paired 2 ...
Differences in NRS scores were calculated using the unpaired t-test. One level injection patients were compared to patients having 鈮 2 levels injected using the paired and unpaired t-test. The proportion of patients reporting significant improvement in each group was calculated. NRS scores were ...
RESULTS: The temperature difference between the cerebral cortex and the axilla was 0.46 +/- 1.04 oC in hyperthermic patients, 0.89 +/- 1.65 C in normothermia patients and 1.04 +/- 0.82 C in hypothermic patients. The temperature difference has statistical significance in each group (unpaired t...

the effect of translational knockdown of the gene. (d) Knockdown of H+–ATPase impaired the acid secretion function (Δ[H+], difference from the background; measured by SIET, for details refer to text) in zebrafish skin. Mean±SD (n=10).*Significant difference (unpairedt-test,p≤0.05)....
Based on the numbers of each mating combination and unpaired individuals, we estimated a vector with the eight parameters by maximizing a likelihood function (see Supplementary Methods). This was accomplished by numerical optimization executed using the mle2 function in the R package bbmle. To ...
采用非配对 t 检验比较两组间的红细胞参数和血小板参 数,采用配对 t 检验比较组内电阻抗法和光学法血小板计数结果。结果 两组血小板参数存在极显著差异,大血小板组的 P- LCR 、 MPV 、 PDW 和 IPF% 均明显高于正常血小板组,而红细胞参数无明显差异。大血小板组电阻抗法和光学法血小板计数差异 有统计学意义( ...
Paired electrons in an atom occur as pairs in an orbital but, unpaired electrons do not occur as electron pairs or couples. The key difference between pair
