Rezultatom, ki jih dobimo, ko želimo z modelom logistične regresije oceniti majhen vzorec, kjer so izidi redki, ne moremo kar tako zaupati. Pri tovrstni analizi se lahko celo zgodi, da ocene parametrov ne obstajajo. To je tako imenovana ločenost oz. monotona funkcija verjetja, saj situacija nastopi, ...

maximum likelihood estimation;logistic regression;Firth’s correction;separation;penalized likelihood;bias;
The parameters of logistic regression models are usually obtained by the method of maximum likelihood (ML). However, in analyses of small data sets or data sets with unbalanced outcomes or exposures, ML parameter estimates may not exist. This situation has been termed ‘separation’ as the two outcome ...

logistic regression;Firth's correction;statistics;
Background: For finite samples with binary outcomes penalized logistic regression such as ridge logistic regression has the potential of achieving smaller mean squared errors (MSE) of coefficients and predictions than maximum likelihood estimation. There is evidence, however, that ridge logistic reg ...

D-dimer;cohort study;factor XI;recurrence;venous thromboembolism;
Essentials Factor XI is a potential target for anticoagulation. The association between factor XI and venous thrombosis recurrence was tested in a cohort study. Low factor XI was associated with reduced risk of recurrent venous thrombosis. A sex-and age-adjusted linear association between D-Dimer an ...

embolism;recurrence;risk factors;thromboembolism;thrombosis;
Patients with unprovoked deep-vein thrombosis (DVT) of the leg or pulmonary embolism (PE) have a high recurrence risk. How often these recurrences are provoked by a temporary risk condition is unknown. In a cohort of patients with unprovoked venous thromboembolism (VTE), we evaluated the clinical ci ...

Background: The use of potentially inappropriate medication (PIM) in population of older adults may result in adverse drug events (ADE) already after short term exposure, especially when it is prescribed to patients with chronic kidney disease (CKD). In order to limit ADE in the treatment of older a ...

Background: Although optimal bowel preparation is essential for high-quality screening colonoscopy, documentation of preparation quality, patient satisfaction and adherence is scarce. Aim: The aim of this article is to compare low-volume (LV, 300 ml sodium picosulfate), intermediate-volume (IV, 2 l ...

Faecal pollution of water and the resulting potential presence of human enteric pathogens is a predominant threat to public health. Microbiological water quality can be assessed by the detection of standard faecal indicator bacteria (SFIB) such as E. coli or certain Enterococcus species. In recent y ...

Background: Patients with spinal cord injury (SCI) are at risk of thrombosis and bleeding. Data on the risks during rehabilitation are inconsistent, and thromboprophylactic strategies are heterogeneous. We aimed to evaluate the thrombotic risk and bleeding events of SCI patients during rehabilitatio ...
