Figure 3From: An investigation of minimisation criteria Sample size 40, 5 prognostic factors (3 binary, 1 3-category, 1 4-category). 95th centiles of the distributions of proportionate changes from expected for randomisation weights from 1 to 100 obtained from 5000 simulations. Dotted lines show results when prognostic factors are weighted according to the number of categories. Results for binary factors shown in black, 3-category in blue and 4-category in purple.Back to article page
