The Editors-in-Chief have retracted this article after concerns were raised about data presented in Tables 2, 4, and 5 and error bars in Figs. 1, 2, 3, 12, 13, 14, and 15. The authors failed to provide raw data and evidence of ethical approval.

The Editors-in-Chief therefore have lost confidence in the data presented in this article.

Authors, Muhammad Shakeel, Farhat Jabeen, and Sadia Zafar do not agree to this retraction. Authors, Rehana Iqbal, Abdul Shakoor Chaudhry, Muhammad Ali, Muhammad Saleem Khan, Adeel Khalid, Samina Shabbir, and Muhammad Saleem Asghar have not responded to any correspondence from the editor/publisher about this retraction.
