From: The Influence of Energy Depletion by Metformin or Hypocaloric Diet on Thyroid Iodine Uptake in Healthy Volunteers: a Randomized Trial

Figure 1

Effects of hypocaloric dieting and metformin on serum TSH, fT4, T3, rT3, the T3/rT3 ratio and T3/fT4 ratio in healthy volunteers before and after intervention. Serum TSH levels were log transformed and differences before and after intervention were determined with paired student’s T tests. *P < 0.05: significant effect of interventions within groups when compared with baseline.
