Dear Sir,
I was interested in the article of Kianpour et al. on reference intervals for thyroid
hormones during the first trimester of gestation from an area with sufficient iodine
level [1]. The unavailability of data in this
population had triggered this study where 436 pregnant and 444 non-pregnant women
were recruited. I appreciate the great effort taken by the authors to recruit such
a
large population for the study. Following screening as per exclusion criteria 291
pregnant women were eliminated and thus the data of 145 pregnant was included for
analysis. However, the article mentions the analysis of samples of 185 patients. The
authors have also calculated the multiples of medians (MoM) to unitise different
laboratory reports.
