For instance, Voss, Rothermund, and Voss (2004), Ratcliff and Rouder (1998), and Wagenmakers et al. (2008) showed that accuracy instructions increase boundary separation, easier stimuli have higher drift rates, and unequal reward rates or presentation proportions are associated with changes in starting point.
Power to detect an intervention effect on unprotected vaginal and anal sex: Power calculations were based on a two-sided Poisson Regression of a dependent variable of counts (i.e., number of unprotected sex acts) on a binary independent variable (Group1 = active risk reduction, Group2 = didactic presentation) with proportion of 0.50 (i.e., 160 participants in each treatment group).
Power to detect an intervention effect on HIV/STI incidence: Power calculations were based on a two-sided Poisson regression of a dependent variable of counts (i.e., number of new STIs) on a binary independent variable (Group1 = active risk reduction, Group2 = didactic presentation) with proportion of 0.50 (i.e., equal number of participants in each group).
However, in a recent analysis of outcome in over 2000 patients undergoing surgery for colorectal cancer, there was no evidence that mode or stage at presentation, the proportion of patients undergoing curative resection or postoperative mortality accounted for the difference in survival between the affluent and deprived patients (Hole and McArdle, 2002).
Proportion of patients with three or more pre-referral consultations; number of days from first presentation to referral; proportion of patients who presented with haematuria and proportion of patients investigated in primary care.
Following initial presentation a small proportion of children with relapsing NS go on to develop steroid dependent disease.
In addition to patients with established co-morbidities at initial presentation, a significant proportion develop co-morbidities over time, such as insulin resistance, dyslipidaemia and hypertension.
Early laboratory risk factors at presentation were neutrophil proportion (95% CI=1.04-1.17), serurearea (95% CI=1.02-1.56) alaninenine aminotransferase level (95% CI=1.001-1.06).
Prioritising all TWW routes above Emergency Presentations reduces the observed proportion of Emergency Presentations by around 1%.
We used a cluster level analysis of the practice specific means and proportions to facilitate presentation of differences in proportions.
