The Editor-in-Chief is issuing an Editorial Expression of Concern for this Article. Since publication, it has been brought to our attention that it significantly overlaps with a number of articles by different authors [1,2,3,4]. After investigation, the authors informed us that the article reports a study which they designed, carried out and coordinated as part of undergraduate project whilst at Landmark University.

As the journal is not in a position to mediate data ownership disputes, the journal has reached out to the institution to confirm who owns the data and clarify the correct authorship. T. F. Adepoju agrees to this Editorial Expression of Concern. B. E. Olatunbosun, O. M. Olatunji and M. A. Ibeh have not responded to any correspondence from the publisher about this Editorial Expression of Concern.
