The authors would like to add the following paragraph in the acknowledgements section of the original version of the paper:

“The work described in this paper is based on studies performed by Pumeza Gogwana as part of her PhD thesis (Gogwana PC, 2014. Investigation of the potential beneficial effects of supplemental polyunsaturated fatty acids and glycosaminoglycans on the risk factors for calcium oxalate kidney stone formation using theoretical, experimental and human models. Doctoral dissertation, University of Cape Town). The authors duly acknowledge this contribution to the present paper”.

So the Acknowledgements section should be:

The financial support of the South African Medical Research Council, the South African National Research Foundation and the University of Cape Town is gratefully acknowledged. The authors would like to extend their appreciation to Johanna van Wyk of the NCDRU of the SAMRC for her invaluable laboratory assistance analyzing plasma and RBC total phospholipid fatty acids. The work described in this paper is based on studies performed by Pumeza Gogwana as part of her PhD thesis (Gogwana PC, 2014. Investigation of the potential beneficial effects of supplemental polyunsaturated fatty acids and glycosaminoglycans on the risk factors for calcium oxalate kidney stone formation using theoretical, experimental and human models.
