odds ratio英语定义 English: The odds ratio (OR) is a statistical measure used in the analysis of the association between two binary variables. It represents the ratio of the odds of an event occurring in one group to the odds of it occurring in another group.In other words, it quantif...
The odds ratio (OR) is one of several statistics that have become increasingly important in clinical research and decision-making. It is particularly useful because as an effect-size statistic, it gives clear and direct information to clinicians about which treatment approach has the best odds of...
In this paper, we propose a new data mining task [4] aimed at specifying the types of patterns or knowledge to be discovered during the data mining process in biomedical applications, where the diagnostic odds ratio can be calculated. Therefore, we define Jumping Diagnostic Odds Ratio Sequential...
To explain how ORs are calculated and what they mean, we will use two examples. Let's first consider a hypothetical example of a randomised controlled trial (RCT). We are often interested in programmes that will reduce rates of smoking in the community. In particular, we often see studies ...
Subsequently, the waist-to-hip ratio (WHR) was calculated as WC (in cm) divided by HC (in cm). Data on the participant’s physical activity (PA) was assessed using the International Physical Activity Questionnaire (IPAQ) through face-to-face interviews [22]. IPAQ is a set of ...
The sizes of the arms of the ith study are n Ti and n Ci ; let N i =n Ti +n Ci and let q i =n Ci /N i . Data in the arms have binomial distributions with probabilities p Ti and p Ci . The effect of interest is the logarithm of the odds ratio θ i = log[p Ti /(...
When the risk ratio cannot be obtained directly (such as in a case-control study), the odds ratio is calculated and often interpreted as if it were the risk ratio. Subsequently, the term relative risk commonly refers to either the risk ratio or the odds ratio. However, only under certain...
LODDS is defined as the logarithm of the probability ratio of positive or negative lymph nodes when one lymph node is detected, which effectively balances the number of ELNs and the number of PLNs [22]. Spolverato et al. reported that the LODDS system (C index: 0.636; AIC: 4304.0) was...
098 unique students in 108,915 programs between the academic years 2010/11 and 2022/23, with 24% of students having multiple enrollments and 26% having pre-studies. Survival analyses showed higher probabilities of graduating in each semester when students had pre-studies. Odds ratio tests ...
Furthermore, odds ratio (OR) analysis showed that risk of rabies (in either the PrEP (OR = 2.91) or PEP (OR = 3.29) groups) is associated with increased odds of being seropositive to Borrelia. However, the difference in Borrelia seroprevalence between groups was not statistically significant...
