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

“…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. …”

Excess pCO2 and carbonate system geochemistry in surface seawater of the exclusive economic zone of Qatar (Arabian Gulf) by Connor, Izumi

“…The slope suggests that removal of C as CaCO3, organic matter (CH2O) or gas exchange (FCO2) is occurring with a ratio of ΔCaCO3/(ΔCH2O or FCO2) = 1:2.86. The tracer Alk*, defined as the deviation of potential alkalinity (AP) (where AP = TA + 1.26 [NO3]) from conservative potential alkalinity ((ApC), (ApC = S Ap′S′ where A'P and S′ are mean values for the whole surface ocean) has values primarily determined by CaCO3 precipitation and dissolution. …”
