The lack of a noticeable effect of the number of pregnancies on the SSR may be partly explained by the influence of birth intervals between pregnancies. In this study sample, birth interval data were available for only a portion of the surveyed women (5,330), but the results indicate a rel...

Figure 1.2 shows the distribution ratio difference, KD2–KD1, needed to obtain a baseline resolution, Rs = 1.5, between the peak of Solute 1 and that of Solute 2, plotted versus the logarithm of the phase ratio. Four sets of k values were examined. It is recalled that the retention fact...
interval, pseudo-CASL and PASL within-subject coefficients of variation were comparable and in the 8–10% range. In another study, the between-session ICC for 12 cognitively intact older subjects (mean age=75.5years) scanned a year apart were 0.74 for gray matter perfusion in the leftmiddle ...
3,14 The regression model of the UPCR versus 24-hour urine protein data suggests a strong and statistically significant correlation between the 2 measurements, and using a UPCR cut-off value of 2.4 to delineate between grade 2 and 3 proteinuria and the need for further testing would obviate ...
Pearson χ2test was used to compare the distribution of categorical variables in different subgroups. Unconditional logistic regression was used to estimate the odds ratio (OR), 95% confidence interval andPvalue for the association between selected characteristics and sex ratio. The models were adjuste...
