    GlossaryInstrumental Variable Analysis

    statistical method to estimate causal effects using external variables

    Instrumental Variable Analysis (IV Analysis) is a statistical method used to estimate causal relationships when controlled experiments are not feasible. It involves using an "instrumental variable" that is correlated with the independent variable but not with the error terms in the model, helping to address issues of endogeneity and confounding variables. This technique is particularly useful in fields like economics and epidemiology, where randomized controlled trials are often impractical.

      community Verteporfin and Microneedling

      in Treatments 6 months ago
      Clinical studies by Dr. Barghouthi and Dr. Bloxham indicate that Verteporfin, when used with FUE and FUT hair transplantation methods, shows promise in hair follicle regeneration and minimal scarring due to its ability to inhibit Yes-associated protein (YAP). Microneedling at depths of 3-3.5mm, combined with Verteporfin, could potentially reactivate dormant follicles, although the optimal dosage and application method are still under investigation. Concerns remain about the DHT sensitivity of regenerated follicles, highlighting the need for further research to optimize trauma levels and Verteporfin concentrations to achieve effective and scar-free hair regeneration.
