Prognostic classification schemes have often been used in medical applications, but rarely subjected to a rigorous examination of their adequacy. For survival data, the statistical methodology to… Expand
Standard graft-versus-host disease prophylaxis with or without anti-T-cell globulin in haematopoietic cell transplantation from matched unrelated donors: a randomised, open-label, multicentre phase 3…
BACKGROUND Graft-versus-host disease (GVHD) is a major cause of morbidity and mortality after allogeneic haematopoietic cell transplantation from unrelated donors. Anti-T-cell globulins (ATGs) might… Expand
Central retinal artery occlusion: local intra-arterial fibrinolysis versus conservative treatment, a multicenter randomized trial.
PURPOSE The reported outcomes of central retinal artery occlusion (CRAO) with or without treatment vary considerably. Although local intra-arterial fibrinolysis (LIF) using recombinant tissue… Expand

The loss of telomere repeats has been causally linked to in vitro replicative senescence of human diploid fibroblasts (HDFs). In order to study the mechanism(s) by which telomere shortening signals… Expand
Chronic graft-versus-host disease: long-term results from a randomized trial on graft-versus-host disease prophylaxis with or without anti-T-cell globulin ATG-Fresenius.
Previous randomized graft-versus-host disease (GVHD)-prophylaxis trials have failed to demonstrate reduced incidence and severity of chronic GVHD (cGVHD). Here we reanalyzed and updated a randomized… Expand
High-intensity versus low-intensity non-invasive ventilation in patients with stable hypercapnic COPD: a randomised crossover trial
Rationale The conventional approach of low-intensity non-invasive positive pressure ventilation (NPPV) produces only minimal physiological and clinical benefits in patients with stable hypercapnic… Expand
A multicenter phase II trial of decitabine as first-line treatment for older patients with acute myeloid leukemia judged unfit for induction chemotherapy
Background The treatment of acute myeloid leukemia of older, medically non-fit patients still poses a highly unmet clinical need, and only few large, prospective studies have been performed in this… Expand
Role of isolated locoregional recurrence of breast cancer: results of four prospective studies.

PURPOSE We evaluated the effect on future prognosis of an isolated locoregional recurrence (ILRR) after the primary diagnosis of breast cancer. Using data from four prospective studies of the German… Expand
Sample size considerations for the evaluation of prognostic factors in survival analysis.
When the role of a new prognostic factor is investigated, careful planning of an appropriate study is required. This includes an assessment of the power of the study in terms of sample sizes. An… Expand
Effect of Availability of Transcatheter Aortic-Valve Replacement on Clinical Practice.

- 16 December 2015
BACKGROUND Since the adoption of transcatheter aortic-valve replacement (TAVR), questions have been raised about its effect on clinical practice in comparison with the effect of surgical aortic-valve… Expand
