• The figures in the upper triangle represent the strength of association between each pair of variables. Where both variables are binary (onset site, gender, riluzole), the OR is given; where one is continuous (age, delay) and one binary, the difference in means is given; where both are continuous, Pearson's r is given. In each case, the 95% CI is given in the corresponding cell in the lower triangle. Figures in bold represent associations for which the CI does not include the null effect (unity for ORs, zero otherwise).
