Influences on numerical density and size of Ery-Is, the degree of anemia, and prognosis of myelodysplastic syndromes (MDS) dependent on the findings on the day of diagnosis: only variables remaining significant in multivariate analyses were presented (the results from univariate analyses and an overview of all the variables taken into consideration are listed in the Online Supplementary Tables S4–S6). Multivariate Poisson and linear regression analyses, analysis of variance components, and Cox proportional hazards regression; stepwise regression; β_i = regression coefficient (Poisson regression); Δμm=change in mean diameter in the case of a subtype, a karyotype aberration, or a one-log increase of the numerical density of Ery-Is. ΔHb=mean change in the hemoglobin (Hb) level of peripheral blood (g/dL) in the case of alterations of erythropoiesis, occurrence of MF, or a del(5q); VC=estimated proportion (in %) of variance in the deviation of the Hb value of peripheral blood from the normal Hb level of the control group attributable to a variable. HR: hazard ratio.
