Power curves for detecting a true log2 fold change with varying sample sizes in (A) plasma DDA-TMT data and (B) serum DDA-TMT data. Each curve represents the statistical power to detect a true difference as a function of log2 fold change for different sample sizes ranging from 11 to 16. The dashed horizontal line represents a 90% power threshold, which is the desired level of power to detect a difference if it truly exists
