The Ranson criteria form a clinical prediction rule for predicting the prognosis and mortality risk of acute pancreatitis. They were introduced in 1974 by the English-American pancreatic expert and surgeon Dr. John Ranson (1938–1995). [1]
Sitagliptin, sold under the brand name Januvia among others, is an anti-diabetic medication used to treat type 2 diabetes. [8] In the United Kingdom it is listed as less preferred than metformin or a sulfonylurea. [9] It is taken by mouth. [8] It is also available in the fixed-dose combination medication sitagliptin/metformin (Janumet, Janumet ...
A 2014 review found increased risk of heart failure with saxagliptin and alogliptin, prompting the FDA in 2016 to add warnings to the relevant drug labels. [22] A 2018 meta analysis showed that use of DPP-4 inhibitors was associated with a 58% increased risk of developing acute pancreatitis compared with placebo or no treatment. [23]
A risk–benefit ratio (or benefit-risk ratio) is the ratio of the risk of an action to its potential benefits. Risk–benefit analysis (or benefit-risk analysis) is analysis that seeks to quantify the risk and benefits and hence their ratio. Analyzing a risk can be heavily dependent on the human factor.
The relative risk (RR) or risk ratio is the ratio of the probability of an outcome in an exposed group to the probability of an outcome in an unexposed group. Together with risk difference and odds ratio , relative risk measures the association between the exposure and the outcome.
It should be clear that the hazard ratio is a relative measure of effect and tells us nothing about absolute risk. [13] While hazard ratios allow for hypothesis testing, they should be considered alongside other measures for interpretation of the treatment effect, e.g. the ratio of median times (median ratio) at which treatment and control ...
Diagnostic odds ratios less than one indicate that the test can be improved by simply inverting the outcome of the test – the test is in the wrong direction, while a diagnostic odds ratio of exactly one means that the test is equally likely to predict a positive outcome whatever the true condition – the test gives no information.
The group exposed to treatment (left) has the risk of an adverse outcome (black) reduced by 50% (RRR = 0.5) compared to the unexposed group (right). In epidemiology , the relative risk reduction (RRR) or efficacy is the relative decrease in the risk of an adverse event in the exposed group compared to an unexposed group.
