STATISTICS NOTES FROM THE BMJ Research Methods & Reporting

Population attributable fraction Percentage differences, symmetry, and natural logarithms What is a percentage difference? Inverse probability weighting Bootstrap resampling methods Uncertainty and sampling error Uncertainty beyond sampling error Statistics Notes: Missing outcomes in randomised trials Brackets (parentheses) in formulas How to obtain the P value from a confidence interval How to obtain the confidence interval from a P value Comparisons within randomised groups can be very misleading Correlation in restricted ranges of data
