Risks and benefits of treating mild hypertension: a misleading meta-analysis?

interventions

Egger M, Smith GD.
GSID: bddYM0Tp36MJ
M Egger, GD Smith - Journal of hypertension, 1995 - journals.lww.com

The benefit gained from antihypertensive treatment can vary widely across different groups of patients. For example, in one randomized trial approximately eight fatal or non-fatal …

Government spending and legislative organization: Quasi-experimental evidence from Germany

quasi-experimental designs

Egger P, Koethenbuerger M.
GSID: uDEolBu2fRwJ
P Egger, M Koethenbuerger - American Economic Journal: Applied …, 2010 - aeaweb.org

… We use panel data from 2,056 municipalities over a period of 21 years and a quasi-experimental design to identify the causal effects of a change in municipality council size on spending. The quasi-experimental design rests upon discontinuities in...

Bias in meta-analysis detected by a simple, graphical test

interventions

Egger M, Smith GD.
GSID: 6J6hwO5nPekJ
M Egger, GD Smith, M Schneider, C Minder - Bmj, 1997 - bmj.com

Objective: Funnel plots (plots of effect estimates against sample size) may be useful to detect bias in meta-analyses that were later contradicted by large trials. We examined whether a …

Who benefits from medical interventions?

interventions

Smith GD, Egger M.
GSID: QetErEw_xkQJ
GD Smith, M Egger - BMj, 1994 - bmj.com

The results of clinical trials are often expressed in relative terms-for example, a particular treatment reduces the risk of an adverse outcome by 40%. Yet knowing that the treatment reduces the risk of such an outcome from 5% to...

Intraoperative neuromonitoring: lessons learned from 32 case events in 2095 spine cases.

Evidence-based spine-care journal

Eager M, Jahangiri F, Shimer A, Shen F, Arlet V.
PMID: 23637670
Evid Based Spine Care J. 2010 Aug;1(2):58-61. doi: 10.1055/s-0028-1100917.

STUDY TYPE:  Restrospective chart review Introduction:  Intraoperative neuromonitoring is becoming the standard of care for many more spinal surgeries, especially with deformity correction and instrumentation. We reviewed our institution's neuromonitored spine cases over the past 4 years to see...

Hypoxic Three-Dimensional Scaffold-Free Aggregate Cultivation of Mesenchymal Stem Cells in a Stirred Tank Reactor.

Bioengineering (Basel, Switzerland)

Egger D, Schwedhelm I, Hansmann J, Kasper C.
PMID: 28952526
Bioengineering (Basel). 2017 May 23;4(2). doi: 10.3390/bioengineering4020047.

Extensive expansion of mesenchymal stem cells (MSCs) for cell-based therapies remains challenging since long-term cultivation and excessive passaging in two-dimensional conditions result in a loss of essential stem cell properties. Indeed, low survival rate of cells, alteration of surface...

Synthesis of Pyrrolidines and Pyrrolizidines with α-Pseudoquaternary Centers by Copper-Catalyzed Condensation of α-Diazodicarbonyl Compounds and Aryl γ-Lactams.

Angewandte Chemie (International ed. in English)

Goudedranche S, Besnard C, Egger L, Lacour J.
PMID: 27701808
Angew Chem Int Ed Engl. 2016 Oct 24;55(44):13775-13779. doi: 10.1002/anie.201607574. Epub 2016 Oct 04.

N-aryl γ-lactams react intermolecularly with acceptor-acceptor diazo reagents, usually dicarbonyl compounds, in a copper-catalyzed process to yield functionalized pyrrolidines with α-pseudoquaternary centers. As 1,2-acyl or -phosphoryl migration is preferred, single regioisomers are obtained. Furthermore, in the presence of a...

The Role of River Morphodynamic Disturbance and Groundwater Hydrology As Driving Factors of Riparian Landscape Patterns in Mediterranean Rivers.

Frontiers in plant science

Rivaes R, Pinheiro AN, Egger G, Ferreira T.
PMID: 28979278
Front Plant Sci. 2017 Sep 20;8:1612. doi: 10.3389/fpls.2017.01612. eCollection 2017.

Fluvial disturbances, especially floods and droughts, are the main drivers of the successional patterns of riparian vegetation. Those disturbances control the riparian landscape dynamics through the direct interaction between flow and vegetation. The main aim of this work is...

Iterative-cuts: longitudinal and scale-invariant segmentation via user-defined templates for rectosigmoid colon in gynecological brachytherapy.

Journal of medical imaging (Bellingham, Wash.)

Lüddemann T, Egger J.
PMID: 27403448
J Med Imaging (Bellingham). 2016 Apr;3(2):024004. doi: 10.1117/1.JMI.3.2.024004. Epub 2016 Jun 20.

Among all types of cancer, gynecological malignancies belong to the fourth most frequent type of cancer among women. In addition to chemotherapy and external beam radiation, brachytherapy is the standard procedure for the treatment of these malignancies. In the...

Core components for effective infection prevention and control programmes: new WHO evidence-based recommendations.

Antimicrobial resistance and infection control

Storr J, Twyman A, Zingg W, Damani N, Kilpatrick C, Reilly J, Price L, Egger M, Grayson ML, Kelley E, Allegranzi B.
PMID: 28078082
Antimicrob Resist Infect Control. 2017 Jan 10;6:6. doi: 10.1186/s13756-016-0149-9. eCollection 2017.

Health care-associated infections (HAI) are a major public health problem with a significant impact on morbidity, mortality and quality of life. They represent also an important economic burden to health systems worldwide. However, a large proportion of HAI are...

Multiterminal Coulomb-Majorana junction.

Physical review letters

Altland A, Egger R.
PMID: 23705723
Phys Rev Lett. 2013 May 10;110(19):196401. doi: 10.1103/PhysRevLett.110.196401. Epub 2013 May 06.

We study multiple helical nanowires in proximity to a common mesoscopic superconducting island, where Majorana fermion bound states are formed. We show that a weak finite charging energy of the center island may dramatically affect the low-energy behavior of...

Electric-dipole-induced universality for Dirac fermions in graphene.

Physical review letters

De Martino A, Klöpfer D, Matrasulov D, Egger R.
PMID: 24856711
Phys Rev Lett. 2014 May 09;112(18):186603. doi: 10.1103/PhysRevLett.112.186603. Epub 2014 May 09.

We study electric dipole effects for massive Dirac fermions in graphene and related materials. The dipole potential accommodates towers of infinitely many bound states exhibiting a universal Efimov-like scaling hierarchy. The dipole moment determines the number of towers, but...
