  1. SUD substance use disorder, TSH thyroid-stimulating hormone, FT4 free thyroxine
  2. Chi-Square Test was conducted to examine a relationship between FT4 and TSH in above and below the reference ranges and gender as well as diagnostic groups
  3. Reference range was set by 95% of healthy population
  4. Entries in bold are significant at 0.05 level
