Fig. 3.

Spearman rank correlations between ALK7 and INHBB transcript levels and clinical traits in lean (n = 90) and obese (n = 90) subjects. Correlation coefficients (r) and their 95% confidence intervals, as derived from Fisher’s z-transformation, are represented by vertical marks and horizontal lines, respectively. Correlations are statistically significant if their confidence interval does not include zero (vertical axes). Corr. Diff. indicates whether correlations between clinical parameters and ALK7 or INHBB were significantly different between lean and obese subjects. Differences in r between lean and obese are significant if either confidence interval does not include r of the other.
