Address reviewer's comments, update and improve NMA
Dr. Ahmed is an expert in this field. We’ve collaborated on a significant network meta-analysis study, where he’s performed the complete analysis and interpreted the results excellently and with clarity. We have two other contracts with him and he has consistently produced top notch work on deadline. We particularly appreciate his responsiveness and commitment to the final project. I couldn’t rate his medical research services higher and look forward to future projects together. Thank you very much, Ahmed!
