ROBIS: A new tool to assess risk of bias in systematic reviews was developed.

Journal of clinical epidemiology

Whiting P, Savović J, Higgins JP, Caldwell DM, Reeves BC, Shea B, Davies P, Kleijnen J, Churchill R.
PMID: 26092286
J Clin Epidemiol. 2016 Jan;69:225-34. doi: 10.1016/j.jclinepi.2015.06.005. Epub 2015 Jun 16.

OBJECTIVE: To develop ROBIS, a new tool for assessing the risk of bias in systematic reviews (rather than in primary studies).STUDY DESIGN AND SETTING: We used four-stage approach to develop ROBIS: define the scope, review the evidence base, hold...

Software Application Profile: PHESANT: a tool for performing automated phenome scans in UK Biobank.

International journal of epidemiology

Millard LAC, Davies NM, Gaunt TR, Davey Smith G, Tilling K.
PMID: 29040602
Int J Epidemiol. 2018 Feb;47(1):29-35. doi: 10.1093/ije/dyx204. Epub 2017 Oct 05.

MOTIVATION: Epidemiological cohorts typically contain a diverse set of phenotypes such that automation of phenome scans is non-trivial, because they require highly heterogeneous models. For this reason, phenome scans have to date tended to use a smaller homogeneous set...

Testing the validity of value-added measures of educational progress with genetic data.

British educational research journal

Morris TT, Davies NM, Dorling D, Richmond RC, Smith GD.
PMID: 30983649
Br Educ Res J. 2018 Oct;44(5):725-747. doi: 10.1002/berj.3466. Epub 2018 Sep 09.

Value-added measures of educational progress have been used by education researchers and policy-makers to assess the performance of teachers and schools, contributing to performance-related pay and position in school league tables. They are designed to control for all underlying...

Challenges and novel approaches for investigating molecular mediation.

Human molecular genetics

Richmond RC, Hemani G, Tilling K, Davey Smith G, Relton CL.
PMID: 27439390
Hum Mol Genet. 2016 Oct 01;25:R149-R156. doi: 10.1093/hmg/ddw197. Epub 2016 Jul 20.

Understanding mediation is useful for identifying intermediates lying between an exposure and an outcome which, when intervened upon, will block (some or all of) the causal pathway between the exposure and outcome. Mediation approaches used in conventional epidemiology have...

A weak instrument [Formula: see text]-test in linear IV models with multiple endogenous variables.

Journal of econometrics

Sanderson E, Windmeijer F.
PMID: 29129953
J Econom. 2016 Feb;190(2):212-221. doi: 10.1016/j.jeconom.2015.06.004.

We consider testing for weak instruments in a model with multiple endogenous variables. Unlike Stock and Yogo (2005), who considered a weak instruments problem where the rank of the matrix of reduced form parameters is near zero, here we...
