The trial ran for 3.3 years, and during this period the relative risk of a "primary event" (heart attack) was reduced by 36% (relative risk reduction, RRR). The absolute risk reduction (ARR), however, was much smaller, because the study group did not have a very high rate of cardiovascular events over the study period: 2.67% in the control ...
The risk difference (RD), excess risk, or attributable risk[1] is the difference between the risk of an outcome in the exposed group and the unexposed group. It is computed as , where is the incidence in the exposed group, and is the incidence in the unexposed group. If the risk of an outcome is increased by the exposure, the term absolute risk ...
It is defined as the inverse of the absolute risk increase, and computed as / (), where is the incidence in the treated (exposed) group, and is the incidence in the control (unexposed) group. [1] Intuitively, the lower the number needed to harm, the worse the risk factor, with 1 meaning that every exposed person is harmed.

The United States Medical Licensing Examination (USMLE) is a three-step examination program for medical licensure in the United States sponsored by the Federation of State Medical Boards (FSMB) and the National Board of Medical Examiners (NBME).

USMLE score. The United States Medical Licensing Examination score (USMLE score) is given to test takers as a 3-digit score. This score is commonly used by hospitals to determine eligibility for residency and fellowship. The three-digit score is based on a theoretical maximum of 300, but this has not been documented by the NBME / FSMB.
Hypovolemic shock is a form of shock caused by severe hypovolemia (insufficient blood volume or extracellular fluid in the body). [1][2] It can be caused by severe dehydration or blood loss. [3][2] Hypovolemic shock is a medical emergency; if left untreated, the insufficient blood flow can cause damage to organs, leading to multiple organ failure.
USMLE Step 3. Step 3 is the final exam in the USMLE series of examinations. It is part of the licensing requirements for Doctors of Medicine (M.D.), including international medical graduates aiming to practice medicine in the United States. Generally, it is a pre-requisite of the majority of the state licensing boards.
An estimated 14% of adults in the study met the criteria for absolute iron deficiency, which results from a severe reduction or absence of iron stored in the body, and an estimated 15% of the ...
