The two primary aims of the analyses were (1) to examine differences in sexual activity and functioning between USS, MMS and control groups over time that were not explained by anxiety trait levels; and (2) to examine the effect of repeat screening and level of this screening on changes in...
High mammographic density is an independent risk factor for breast cancer by poorly understood molecular mechanisms. Women with dense breasts often undergo conventional magnetic resonance imaging (MRI) despite its limited specificity, which may be increased by diffusion-weighted imaging (DWI) with apparent...
As explained in Royston and White (2011), the chained equations method imputes missing values in different steps: initially, all missing values are filled at random. The first variable with at least one missing value, say smoking, is then regressed on the other variables including those with ...
The company plan for Guatemala made clear the role of central direction in this coordinated lobbying effort: 'Maintain a constant direct monitoring of government and congress activities on new taxes, tariffs and excise structures and values procuring information from the source, following strategies ...
We also calculated sensitivity, specificity, positive- and negative-likelihood ratios (LR+ and LR−) and the positive and negative predictive values (PPV and NPV) using a cutoff value for each risk score chosen such that 10% of the population had values above the cutoff; the procedure was ...
The cells were incubated with JC-1 at 37°C in the dark for 1 h, then analysed with a flow cytometer (Flomax, Partec, Münster, Germany). Statistical analysis Luciferase activity, densitometric values and the number of migrated cells were analysed by analysis of variance, with P<0.05 ...

DM and KS: The Blood Safety, Hepatitis, Sexually Transmitted Infections (STI) and HIV Service has provided GSK with post-marketing surveillance reports on HPV infections; a cost recovery charge is made for these reports. HK: Former chair of the Advisory Committee for Cervical Screening (Public ...
All statistical tests were two-sided, and P-values of<0.05 were considered to be statistically significant. Results First- and second-degree relatives of NPC probands were followed for a median of 49.0 years and 33.2 years, respectively (Table 1). A bimodal pattern in age at study entry ...
The beta-value of each of these CpG islands was transformed to an M-value (Du et al, 2010), and the distribution of M-values for each data set was plotted and found to be bimodal. For each CpG island, a threshold was determined at the point between the two modes to dichotomise ...
