^{a}Correlations in entrants to medical school between measures of academic and professional attainment in the UCLMS Cohort Study.
^{b}Correlations above the diagonal are simple Pearson correlations and have different values of n for various reasons.
^{c}Correlations shown in bold are significant at P<0.05.
^{d}Correlations in the lower triangle involving censored variables were corrected for censoring using an MCMC method, with 95% confidence intervals calculated from the final 2000 MCMC steps in a chain of 5000.
^{e}Values in these two columns are mean ± SE (95% CI) unless otherwise stated.
*Indicates correlations below the diagonal, which are based on two non-censored, continuous variables and therefore identical to those above the diagonal.
