The focus of the 4 papers presented (one published, 3 manuscripts) is assessment of the effect of genetic variants on mortality and complications in diabetes patients, and has therefore required accessing genotypical as well as phenotypical information from several studies. The genotypical information acquisition seems well described (however I have very limited knowledge in this field), whereas the phenotypical (clinical) information is less consistently reported between studies. In general the epidemiological analyses appear weak and not well explained in the papers, in particular the second paper (``Shared genetic'') has flaws in the explanation of methods as well as inconsistent event counts (12% extra deaths appear). Moreover the fourth paper has severe methodological omissions that possibly invalidates the conclusions even though this question could have been resolved quite easily (with unknown result, though). Also it seems odd to make the last two papers (on the DOLCHE study) separate, the famine analysis could easily have been included in the first paper - it is basically a single extra variable (although pointing at different loci). In conclusion, I find the amount of work presented adequate, but I find it difficult to recommend to the University of Lund to pass a PhD with two major flawed manuscripts out of 4.
