Among traced families, those whose children walked using aids or could not walk were significantly less likely to refuse; (OR for refusal compared to children who walked without aids = 0.5, 95%CI: 0.4 to 0.8 and 0.6, 95%CI: 0.4 to 0.9 respectively).
Refusals were compared to participants for age and housing type.
Trump's refusal should be compared to Hillary's refusal to release her Goldman Sachs speech transcript.
OR of cubicle refusal in heifers compared to cows: 13.29 (c.i.95%OR = 7.89 22.61, P < 0.01) The total incidence rate of mastitis during the first 30 days after calving was 8.7%.
Participants randomized to detailed written consent also had a significantly higher refusal rate (23%) when compared to those in the limited written group (12%; mean difference between groups −11%, 95%CI−21%1% to −1%).
No individual measure predicted refusal when participants were compared to the Informant Only group, although the block of variables did make a significant contribution.
In terms of dropping out of the study, we expect rates to be low, as there are much more advantages for agreement to participate compared to a refusal: Patients will get in-depth diagnostic assessments and allowances for filling in the questionnaires or taking part in follow-up assessments (20€ for each time point of measurement).
These refusal rates need to be interpreted slightly differently compared to "traditional" response rates, since they reflect refusals after persons agreed to listen to what the interviewer proposes and if the person fits the target population.
A total of 822 persons approached refused to participate, and the refusal rate was higher in urban (76%, n=681) compared to rural areas (36%, n=141).
The following hypothesis will be tested: (2) A low response rate of migrants compared to non-migrants is related mainly to refusals, language problems, and address-related reasons.
