Fig. 4From: Maternal smoking and high BMI disrupt thyroid gland developmentStatistically significant (P < 0.05) effects of maternal BMI on a circulating hormones, b immunohistochemistry scores, and c transcripts. Shaded areas in a and c represent 95% confidence intervals. Immunohistochemistry scoring proportions in b are shown as stacked percentages for each scoring (“−, unstained” < “(+)” < “+” < “++, more stained”) across gestation. Arrowheads indicate significant (P < 0.05) increase (▲) or decrease (▼) by gestational age. P values associated with changes in relation to smoke exposure are provided in the merged graph panelsBack to article page
