Additional file 2: of Vitamin D deficiency as a risk factor for dementia: a systematic review and meta-analysis

Sensitivity analysis. Figure S1. Knekt et al. [1] removed due to use of different cut-offs to classify vitamin D; Figure S2. Graf et al. [2] removed for reasons of no adjustment for seasonal vitamin D changes, adjustment for presence of ApoE Îľ4 genotype, elderly population, and a population with partly mild cognitive impairments at baseline; Figure S3. Graf et al. [2] and Littlejohns et al. [3] removed due to older populations; Figure S4. Littlejohns et al. [3] and Schneider et al. [4] removed due to use of liquid chromatography-tandem mass spectrometry (LC-MS/MS) to measure serum vitamin D concentrations; Figure S5. Knekt et al. [1] and Schneider et al. [4] removed due to use of dementia leading to hospitalisation as endpoint. (DOCX 152 kb
