  1. Association between value statements and likely influence on length of life indicated in brackets (prolong, shorten, neutral)
  2. A priori, correlations indicated ↑ were expected to be strongly positive and correlations indicated ↓ were expected to be strongly negative
  3. P values are written under correlation coefficient
