These sample sizes gave us 80% power to detect a strength of correlation between two variables (Pearson product moment correlation coefficient) of 0.27 (UK sample), 0.34 (NL sample) 0.21 (combined sample) respectively for the recording of foot inspections and 0.33 (UK sample), 0.40 (NL sample) 0.27 (combined sample) respectively for the prescription of statins, assuming a type 1 error rate of 5%.
