REPRODUCIBILTY OF THE 75G ORAL GLUCOSE TOLERANCE TEST FOR THE DIAGNOSIS OF GESTATIONAL DIABETES MELLITUS IN A SUB-SAHARAN AFRICAN POPULATION (DOI: 10.1186/s13104-017-2944-7) The authors evaluated the reproducibility of 75g oal glucose tolerance test and factors associated with non-reproducible results in Cameroonian pregnant women. The objectives was clearly and well pursued in the study. The methodology section was well done. And the description or presentation of this section allowed the study to be easily repeated (internal validity). The exclusion criteria which included women with known history of diabetes mellitus, as well as those with long term medical traetments, on steroids and beta-mimetics or presenting with any medical complications (like severe malaria, hyperemesis gravidarum, pyelonephritis) were excluded (it was clearly stated in the paper). The statistical analyses was presented in detail. However, the results section would have been better with more tables (so that the readers can digest huge information within a short time). Table one would have been better with inclusion of 95% confidence intervals and p-values. Also a seperate table pointing to the 95% confidence interval and p-values will be desirable (not only percentage as done in the study). The results complement the conclusion. The limitations of the study were spelt out regarding the generazability of the study (always prudent to consider this and bring it forward clearly). There must be some form strength in this study, this must be brought out as well.
