Some research analyzed modifications in miRNA levels among fewer than 30 breast cancer and 30 handle samples in a single patient cohort, whereas other individuals analyzed these changes in considerably larger patient cohorts and validated miRNA signatures making use of independent cohorts. Such differences affect the statistical power of analysis. The miRNA field must be conscious of the pitfalls related with tiny sample sizes, poor experimental style, and statistical selections.?Sample preparation: Complete blood, serum, and plasma have been employed as sample material for miRNA detection. Entire blood consists of several cell types (white cells, red cells, and platelets) that contribute their miRNA content towards the sample becoming analyzed, confounding interpretation of outcomes. For this reason, serum or plasma are preferred sources of circulating miRNAs.
