There was a significant positive correlation in the entire study population between E2% and IR% (r=0.72, p=0.001, r2 0.51) that remained when adjusted for age (p=0.028), BMI (p=0.001), and preoperative insulin sensitivity (p=0.011) separately. Premenopausal women developed a higher degree...
CV可以用于估计模型的泛化性能。 R-squared(R2):决定系数,表示因变量的变异中可以由模型解释的部分比例。R2值范围从0到1,越接近1表示模型能够更好地解释因变量的变异性。 Adjusted R-squared(Adj.R2):调整后的决定系数,考虑了模型中自变量的数量。它通过惩罚模型中不必要的自变量来避免过拟合,通常在比较不同模型...
DATA ANALYSIS The absolute difference between the RR intervals of successive heart beats was used as a measure of short-term variability. It was calculated as where RR is the time in milliseconds from the peak of one R wave the next- and "n" the number. For each study, the RR interval...
We used adjusted bivariate linear regression to examine the relation between milk-fat percentage and child 25(OH)D and zBMI concurrently. Effect modification by milk volume consumed on the evaluated relations was explored with the use of an interaction term in the statistical model. Results: Among...
In addition, body mass index (beta = 0.25, P < 0.05) and waist-to-hip ratio (beta = 0.21, P < 0.05) were found to be significantly correlated with CRP (adjusted R2 = 12%, P < 0.05), independently of other factors. There was no correlation between FMD and CRP.As a marker of ...
Estimates of r2 mirrored the findings in Figure 2a, in that at a pulse pressure of 69 mm Hg (up to 73 mm Hg), the variance of CRAE explained by pulse pressure in the multivariable-adjusted models increased from ~ 1% below 69 mm Hg to 2% at and above this threshold. We therefore ...

There is no evidence of any connection between networks’ coordination by Primary Health Care and tuberculosis avoidable admissions. Conclusion The results show that progress has been made regarding the coordination of the Health Care Networks, and a positive trend has been shown, even though the ...

The pattern of changes in [18F]THK5317 retention was heterogeneous across all patients, with qualitative differences both between the two AD groups (prodromal and dementia) and among individual patients. High [18F]THK5317 retention was significantly associated over time with low episodic memory ...
