Direct observation comparisons from the Chi-square statistical test identified no significant differences in the area-level PA between schools during lunchtime breaks at baseline for the proportion of children in sedentary behaviour, moderate intensity PA (MPA) and vigorous intensity PA (VPA).
The model also requires baseline estimates for proportions of patients with dyspnoea, cough and sputum, exacerbation rate, forced expiratory volume in one second (FEV1), and exercise capacity measured by the 6-min walk test (6MWT).
Based on the 79-month results, 3 and adjusting for baseline function, the proportion of patients for whom insufficiency persisted, resolved, developed and for whom sufficiency persisted were estimated for each trial arm.
For the purposes of power calculations we estimated the baseline referral proportion of 1% for genetic counseling, 77% for breast cancer screening, 59% for colon cancer screening based on a random sample of patient charts prior to launch of the MeTree tool in the implementation clinics and the CDC's Behavioral Risk Factor Surveillance System Survey data for North Carolina [ 8].
Notably, in the work by Sellam et al. [ 9], the mean baseline CD27+ proportion was 26.8% for rituximab responders and 35.9% for nonresponders.
In the first stage, we estimated facility-level residuals by fitting a logistic regression model and including terms to adjust for baseline value (corresponding proportion of visits in 2009), average annual client load (<10000, 10000+) and rural/urban status.
Chi-square tests were used to compare sex, race, and baseline income proportions for children included in the study with those of children excluded from the study because of lack of a recorded BLL.
At baseline, the proportion of patients receiving prescriptions for each initial statin dose closely matched the claims data (Table 3).
A sample weight was developed for the longitudinal sample as the ratio of baseline sample proportion in a given age-sex cell over the longitudinal sample proportion in that cell, multiplied by the baseline weight.
Means with SD for continuous baseline characteristics and proportions for categorical characteristics were calculated by quintile of total iron and heme iron intake.
