Students in both social and natural sciences often seek regression methods to explain the frequency of events, such as visits to a doctor, auto accidents, or new patents awarded. This book, now in its second edition, pro...

We performed a Monte Carlo study to evaluate the effect of the number of events per variable (EPV) analyzed in logistic regression analysis. The simulations were based on data from a cardiac trial of 673 patients in whic...

ObjectiveSystemic inflammatory response plays a key role in the pathogenesis of endometriosis. This study aimed to investigate the association between the aggregate index of systemic inflammation (AISI), defined as neutr...

Economic inequality is a social phenomenon with several facets, all of which are signifificant when it comes to multidimensional measurement. When income is used as the fundamental variable of analysis to measure economi...

An effective method of traffic state classification is crucial for managing urban traffic congestion. Existing methods usually assume a given number of state categories, which is not flexible if real applications are req...

Abstract Petroleum engineers must accurately determine bubble point pressure (Pb) to optimize oil field development from discovery to abandonment. Errors in predicting this parameter can lead to inaccurate reservoir and ...

With the advancement of urbanization, the intensification of urban population agglomeration has been associated with a gradual decline in the quality of urban ecological systems in many cases. Urban ecological resilience...

Abstract Background Fibroblast growth factor (FGF)‐23 is increased first in the sequence of changes associated with chronic kidney disease (CKD)‐mineral and bone disorder. Thus, its measurement may serve as a predict...

Although logistic regression is the most popular for modelling regression relationships with binary responses, many find relative risk (RR), or risk ratio, easier to interpret and prefer to use this measure of risk in re...

Abstract Background The primary objective of this study is to identify independent risk factors associated with secondary pulmonary hypertension (PH) in silicosis patients through retrospective statistical analysis and t...

Abstract Background Dietary behaviors during adolescence greatly influence lifelong health habits, with patterns and nutritional deficiencies at this stage potentially carrying into adulthood and affecting long-term heal...

Background: We investigated factors related to pitching performance—defined by pitch velocity and accuracy—based on baseball experience, pitching workload, anthropometrics, and range of motion and strength (grip and ...

Abstract This study explored the different categories of parenting concerns and their influencing factors in young and middle-aged breast cancer patients. 490 young and middle-aged breast cancer patients were recruited f...

ObjectiveTo investigate the association of serum N-terminal pro-brain natriuretic peptide (NT-proBNP), red cell distribution width (RDW), homocysteine (Hcy), and clinical parameters with new-onset atrial fibrillation (NO...

Abstract Background Iron overload promotes atherosclerosis in mice and causes vascular dysfunction in humans with Hemochromatosis. However, data are controversial on whether systemic iron availability within physiologica...

The main objective of this Campbell systematic review was to provide a systematic review of the evidence on the effects of microcredit on women's control over household spending in developing countries. More specifically...

Abstract Background Acetabular fractures, predominantly caused by high-energy trauma, pose a substantial healthcare burden in low- and middle-income countries (LMICs) such as Nepal. This study aimed to characterize the e...

Abstract The accurate prediction of the deterioration of Continuously Reinforced Concrete Pavement (CRCP) is essential for the effective management of pavements and the maintenance of infrastructure. In this study, a co...

Abstract Background Environmental dust exposure is common in arid regions and may influence upper airway function. Its relationship with voice quality in young adults remains incompletely understood. Objective To evaluat...

ABSTRACT Objective Although the Musculoskeletal Tumor Society (MSTS) score, Toronto Extremity Salvage Score (TESS), and Knee Society Score (KSS) are widely used for postoperative functional evaluation in patients undergo...

This Campbell systematic review examines the effectiveness of farmer field schools in improving intermediate outcomes (such as knowledge and pesticide use) and final outcomes (such as agricultural yields, incomes and emp...

Abstract Objective This study aimed to systematically identify and validate KIF15 as a potential diagnostic and prognostic biomarker in colon cancer (CC) using integrated bioinformatics analyses. We further explored its ...
