TL;DR: Proposed models for covid-19 are poorly reported, at high risk of bias, and their reported performance is probably optimistic, according to a review of published and preprint reports.
Journal ArticleDOI
A simple formula for the calculation of sample size in pilot studies
Wolfgang Viechtbauer,Luc J.M. Smits,Daniel Kotz,Luc Budé,Mark Spigt,Jan Serroyen,Rik Crutzen +6 more
TL;DR: A simple formula is presented to calculate the sample size needed to be able to identify, with a chosen level of confidence, problems that may arise with a given probability.
Journal ArticleDOI
Short interpregnancy intervals and unfavourable pregnancy outcome: role of folate depletion.
Luc J.M. Smits,Gerard G.M. Essed +1 more
TL;DR: It is suggested that postpartum supplementation with folic acid might prevent excess risk of unfavourable pregnancy outcome in women with short interpregnancy intervals.
Journal ArticleDOI

Ewka C.M. Nelissen,Aafke P.A. van Montfoort,Edith Coonen,Josien G. Derhaag,Joep P.M. Geraedts,Luc J.M. Smits,Jolande A. Land,Johannes L.H. Evers,John C.M. Dumoulin +8 more
TL;DR: The hypothesis that in vitro culture of embryos during the first few days of preimplantation development affects perinatal outcome of IVF singletons and twins is supported and might be an important factor explaining the poorer perinnatal outcome after assisted reproduction technology (ART).
Journal ArticleDOI
Influence of SERTPR and STin2 in the serotonin transporter gene on the effect of selective serotonin reuptake inhibitors in depression: a systematic review
Kim M. Smits,Luc J.M. Smits,Jan S. A. G. Schouten,Foekje Stelma,Patricia J. Nelemans,Martin H. Prins +5 more
TL;DR: Current information is insufficiently reliable as a basis for implementing genetic testing in the diagnostic work-up of the depressive patient, according to a systematic review of the literature on the influence of polymorphisms in the serotonin transporter gene.
