    I read this article with great interest and I have to congratulate the authors.
    However, It is not obvious is the methods how they approached the patients and how the patients were consented. It is var difficult to convey such study in Sudan with Polish scientists without one of the local researchers. Importantly in the ethics section authors mentioned that they received ethical clearance from Poland, we do respect this but is it valid to have an ethical clearance from Poland and fostered the study in Sudan?
    I hope authors would to be able to clarify these points
    Best Regards

    Thank you for your interest in our paper. We would like to explain that our research was carried out during a scientific expedition organized by the Museum of Archaeology in Gda¿sk (MAG) (Poland). Since 1996, MAG has had a long-term concession for surface and excavation works in the region of the 4th Cataract on the right bank of the Nile, granted by the National Corporation for Antiquities and Museums (NCAM) in Khartoum. The expedition was led by the director of MAG, Henryk Paner. Our research is a part of a large-scale archaeological inventorisation of the middle Nile region, initiated by NCAM because of the intended dam erection in the area of Umm Duwemi village and Merowe Island. The aim of the campaign was to rescue cultural heritage and protect monuments in the areas to be flooded after the dam erection.
    We received invaluable help in our efforts from dr Mahmoud el Tayeb, a Sudanese archaeologist living in Poland. Our gratitude towards him was expressed in the article in the Acknowledgements section.
    Due to a high rate of illiteracy in the analyzed cohort, only oral consent for the participation in the study was obtained, in the presence of the local authorities representative.
    The above information was included in our other articles from this series.
