Review: A gentle introduction to imputation of missing values
A. Rogier T. Donders,A. Rogier T. Donders,Geert J. M. G. van der Heijden,Theo Stijnen,Karel G.M. Moons +4 more
TL;DR: In this paper, the authors show that both single and multiple imputations of missing data almost always result in biased estimates, and they also explain and illustrate why two commonly used methods to handle missing data, i.e., overall mean imputation and the missing-indicator method, almost always yield biased estimates.
Journal ArticleDOI
Imputation of missing values is superior to complete case analysis and the missing-indicator method in multivariable diagnostic research: A clinical example
Geert J. M. G. van der Heijden,Geert J. M. G. van der Heijden,A. Rogier T. Donders,A. Rogier T. Donders,Theo Stijnen,Karel G.M. Moons +5 more
TL;DR: In multivariable diagnostic research complete case analysis and the use of the missing-indicator method should be avoided, even when data are missing completely at random.
Journal ArticleDOI
Declining risk of colorectal cancer in inflammatory bowel disease: an updated meta-analysis of population-based cohort studies.
M. W. M. D. Lutgens,Martijn G.H. van Oijen,Geert J. M. G. van der Heijden,Frank P. Vleggaar,Peter D. Siersema,Bas Oldenburg +5 more
TL;DR: The risk of CRC is increased in patients with IBD but not as high as previously reported and not in all patients, and this decline could be the result of aged cohorts.
Journal ArticleDOI
Ultrasound therapy for musculoskeletal disorders: a systematic review.
Daniëlle A W M van der Windt,Geert J. M. G. van der Heijden,Suzanne G.M. van den Berg,Gerben ter Riet,Andrea F. de Winter,Lex M. Bouter +5 more
TL;DR: There seems to be little evidence to support the use of ultrasound therapy in the treatment of musculoskeletal disorders, and the findings for lateral epicondylitis may warrant further investigation.
Journal ArticleDOI

Lisa Ruepert,A. Otto Quartero,Niek J. de Wit,Geert J. M. G. van der Heijden,Gregory Rubin,Jean W M Muris +5 more
TL;DR: Evaluating the efficacy of bulking agents, antispasmodics and antidepressants for the treatment of irritable bowel syndrome found a beneficial effect for antidepressants over placebo for improvement of abdominal pain and subgroup analyses for different types of anti-inflammatory agents found statistically significant benefits.
