Some studies analyzed adjustments in miRNA levels in between fewer than 30 breast cancer and 30 handle samples in a single patient cohort, whereas other folks analyzed these alterations in a lot larger patient cohorts and validated miRNA signatures utilizing independent cohorts. Such variations influence the statistical energy of evaluation.

Complete blood consists of various cell sorts (white cells, red cells, and platelets) that contribute their miRNA content for the sample getting analyzed, confounding interpretation of final results. For this reason, serum or plasma are preferred sources of circulating miRNAs.
