Published 18 January 2021 Att forskningsresultat ska kunna upprepas är en av vetenskapens grundläggande principer. Ändå visar flera genomgångar av vetenskapliga studier att det inte ser ut så. Kritiker pekar på flera orsaker och nu vill forskare minska fokus på publiceringshetsen för att minska felaktigheter. Hör mer på https://sverigesradio.se/artikel/7647634.

Published 18 January 2021 Traumatic brain injury (TBI) is a major cause of disabilities and mortality worldwide, with higher prevalence in offender populations than in the general population. Previous research has strongly advocated increased awareness of TBI in offender populations. The aim of this study was to explore the prevalence and characteristics of TBI, and to investigate associations and

Published 18 January 2021 The Kingdom of Crystal, an area in southern Sweden famous for its many glassworks, is historically heavily burdened by pollution from this industry. Glass crust containing cadmium (Cd), lead (Pb), and arsenic (As) has been deposited around the area and used as filling. The purpose of this study was to monitor whether the high levels of metals in the contaminated soil were

Published 19 January 2021 It has been suggested that high intake of added sugar and sugar-sweetened beverages (SSBs) increase the level of circulating inflammatory proteins and that chronic inflammation plays a role in type 2 diabetes (T2D) development. We aim to examine how added sugar and SSB intake associate with 136 measured plasma proteins and C-reactive protein (CRP) in the Malmö Diet and Ca

Published 20 January 2021 Data were obtained from the prospective, longitudinal, population‐based Children of Western Sweden cohort, which focused on children born in 2003. The parents answered questionnaires at six months and one, four, eight and 12 years of age. Personal identity numbers linked 3634 children to the Swedish Prescribed Drug Register (SPDR) and the National Patient Register (NPR).

Published 20 January 2021 Quality in medical research has recently been criticized for being low, especially in observational research. Methodology is increasingly difficult, but collaboration between clinical researchers and biostatisticians may improve research and reporting quality. The aim of this study is to quantify the value of a biostatistician in the team of authors. Read more at Is repor

By anna [dot] axmon [at] med [dot] lu [dot] se (Anna Axmon) - published 10 June 2021 Concerns have been expressed over standards of statistical interpretation. Results with P <0.05 are often referred to as ‘significant’ which, in plain English, implies important. This leads some people directly into the misconception that this provides proof that associations are clinically relevant. Read the pape

By anna [dot] axmon [at] med [dot] lu [dot] se (Anna Axmon) - published 17 June 2021 Standard errors are usually calculated based on assumptions underpinning the statistical model used in the estimation. However, there are situations in which some assumptions of the statistical model including the variance or covariance of the outcome across observations are violated, which leads to biased standar
