This paper evaluates 29 methods for obtaining a two-sided confidence interval for a binomial proportion (16 of which are new proposals) and comes to the conclusion that: Wilson's classic method is only optimal for a confidence of 99%, although generally it can be applied when n50; for a ...

P-values were computed using two-tailed ‘N-1’ Chi-squared test with 95% confidence interval. Asterisks represent P-values < 0.0001. b) RNA-expression of genes connected to different classes of 2i-specific enhancers. cHiC was used to assign enhancer–promoter connections. Box=5-75th ...
Find the critical value for a right-tailed test with α = 0.01 and n = 75. For parts a and b, use the t tables, software, or a calculator to estimate : a. What is the critical value of t for a 99% confidence interval with...
Pooled odds ratios (95% confidence interval) for the association between the MEDAS score (high adherence vs. low adherence) and malnutrition, stratified by characteristics of study participants. Logistic regression models adjusted for age, sex, educational level (≤primary and secondary or university)...
Odds ratios (OR) were calculated with 95% confidence intervals (CI). Two-tailed p values of <0.05 were considered statistically significant. 3. Results Three hundred and sixty-five patients who completed at least 2 doses of SARS-CoV-2 mRNA vaccination met the inclusion criteria – 231 (63.3...
In the pilot PfSPZ-CVac(PYR + CQ) group (to test safety), 0/2 participants were protected; in the main PfSPZ-CVac(PYR+CQ) group, 2/9 (22.2%, P = 0.8) participants were protected; in the PfSPZ-CVac(CQ) group, 4/5 (80%, P = 0.048; 95% confidence interval, 1–99%) ...
Logistic regression was used to assess the factors associated with the development of clinical competence using a p-value < 0.05 confidence interval. Results Forty-seven percent (47%) of the students were found to be competent while more than half (53%) were not. A Chi-square test ...
