Abstract

Aims/Introduction: The aim of the present study was to investigate the association between diabetes and the risk of all type dementia ( ATD ), A lzheimer's disease ( AD ) and vascular dementia ( VaD ). Materials and Methods: Prospective observational studies describing the incidence of ATD , AD and VaD in patients with diabetes mellitus were extracted from PubMed, EMBASE and other databases up to January 2012. Pooled relative risk ( RR ) estimates and 95% confidence intervals ( CI s) were calculated using the random‐effects model. Subgroup analyses and sensitivity analysis were also carried out. Results: A total of 28 studies contributed to the analysis. Pooled RR of developing ATD ( n = 20) was 1.73 (1.65–1.82, I 2 = 71.2%), AD ( n = 20) was 1.56 (1.41–1.73, I 2 = 9.8%) and VaD ( n = 13) was 2.27 (1.94–2.66, I 2 = 0%) in patients with diabetes mellitus. Higher and medium quality studies did not show any significant difference for pooled RR for ATD , AD or VaD . Sensitivity analyses showed robustness of pooled RR among ATD , AD and VaD , showing no single study had a major impact on pooled RR . Conclusions: The results showed a 73% increased risk of ATD , 56% increase of AD and 127% increase of VaD in diabetes patients.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
