When we performed survival analysis according to the four groups classified by the thyroid function (quartile of each TSH, free T4 and T3) and VA status (i.e., VA—highest quartile of thyroid function, VA—lowest quartile of thyroid function, non-VA—highest quartile of thyroid function and non-VA—lowest quartile of thyroid function), VA with the highest quartile of TSH patients showed a trend for lower event-free survival as compared to those with VA with the lowest quartile of TSH and non-VA patients irrespective of TSH quartile ( Figure S1A ).
