Citation Clark DA. The power of observation. Am J Reprod Immunol 2011; 66: 71-75 Problem  In the golden age of evidence-based medicine, how should one view the cohort-controlled study of IVIG + anti-TNF-α (Humira) in recurrent in vitro fertilization (IVF) failure patients with an elevated Th1/Th2 cytokine production ratio. Method  Critical analysis of the nature of evidence for causation. Results A better delivery rate and a live birth rate per embryo approaching the estimated maximum possible in patients whose elevated Th1/Th2 ratio corrected to normal compared to those with an incomplete correction is a strong argument for causation. A maximal improvement when treatment was given 61-120 days before embryo transfer suggests a possible mechanism via improving the physiology during follicle development. Conclusion  Independent replication to verify results would augment power.
