    Overconfident results with the bivariate random effects model for meta-analysis of diagnostic accuracy studies by Furuya-Kanamori, Luis

    Published 2022
    “…Diaz found that the performance of the bivariate model deteriorates when between-study heterogeneity increases and the number of studies decrease.5 Our simulation studies found similar results—with moderate levels of heterogeneity (tau2 = 1), the coverage probabilities of Se, Sp, and the diagnostic odds ratio (DOR) with the bivariate model dropped below the nominal level.6 Diagnostic accuracy studies usually favor sensitivity over specificity, or vice versa leading to diagnostic 2 × 2 tables with one or more of the cells with low frequency or zero counts. …”

    25-Hydroxyvitamin D serum levels inversely correlate to disease severity and serum C-reactive protein levels in patients with hidradenitis suppurativa by Moltrasio, Chiara

    Published 2021
    “…Vitamin D exerts functions in skin physiology by modulating keratinocyte proliferation and different immunoregulatory processes.1 In several dermatoses, vitamin D correlates to disease severity and is significantly lower if compared to healthy subjects.2 Hidradenitis suppurativa (HS) is a chronic inflammatory disease characterized by painful suppurating lesions mainly localized in the folds.3 Kelly et al.4 conducted the first study assessing vitamin D status in HS, concluding that 75% of patients had vitamin D levels of less than 50 nmol/L compared to 40% of the general population. …”
