  1. Abbreviations: aAH5, Abbreviated AH5; A-level, Advanced level; BMS, Basic medical sciences; GCSE, General Certificate of Secondary Education; MCMC, Markov Chain Monte Carlo; MRCP(UK), Membership of the Royal College of Physicians of the United Kingdom.
  2. aCorrelations in entrants to medical school between measures of academic and professional attainment attainment in the 1990 Cohort study.
  3. bCorrelations above the diagonal are simple Pearson correlations (for example, point-biserials, φ correlations, where a measure is binary or ordinal), and have different n values for various reasons.
  4. cCorrelations shown in bold are significant at P<0.05.
  5. dCorrelations in the lower triangle were calculated taking account of censoring, and for ordinal values are equivalent to tetrachoric/biserial/polychoric correlations.
  6. eValues are mean ± SD (95% CI) unless otherwise stated, and the 95% CIs are the result of the final 2000 MCMC steps in a chain of 5000.
