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 ...

Logistična regresija se uporablja za preučevanje povezanosti med binarno odzivno spremenljivko (nek dogodek se zgodi ali pa ne) in množico neodvisnih spremenljivk. Z mo-delom lahko napovemo verjetnosti dogodka za nove enote, po-gojno na vrednosti neodvisnih spremenljivk. Poleg tega ocene parametrov ...

Background: Practice guidelines recommend patient management based on scientific evidence. Quality indicators gauge adherence to such recommendations and assess health care quality. They are usually defined as adverse event rates, which may not fully capture guideline adherence over time. Methods: F ...

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 ...

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 ...

medications;chronic kidney disease;adverse drug events;pharmaco-epidemiology;older adults;
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 ...

Objectives: Secondary prevention is crucial for reducing morbidity and mortality in patients following acute myocardial infraction (MI). However, adherence to cardiac rehabilitation (CR) and pharmacotherapy remains suboptimal despite strong guideline recommendations. This study investigated the adhe ...
