Answer:
1. Odd ratio:
- Advantages: May be reported in cohort studies, case-control designs and clinical trials.
- Disadvantages: Bad estimation of the risk in situations where the initial risk is high. Difficult to interpret.
2. Relative risk:
- Advantages: Easy to interpret.
- Disadvantages: Not available for case-control designs. Adjustment of the covariance is a hard task.
Explanation:
An odds ratio is a statistical measure used to compare the relative odds of the event/outcome (disease or disorder) with respect to a given variable of interest (e.g. medical history). An odd ratio may be interpreted as though it was a relative risk and therefore this value may lead to error. On the other hand, a relative risk (RR) is a statistic that measures the ratio between the likelihood of an event in an exposed group (disease or disorder) with respect to the likelihood of an event in an unexposed comparison group. Both statistics compare the relative probability of an event/outcome between two comparison groups. The relative risk can not be used in case-control designs because information about the total number of exposed people is not available.
Answer:
Acute otitis media (AOM) is an ear infection which occurs due to inflammation or infection of the area behind the eardrum known as middle ear.
There are few important guidelines to understand when choosing an
antibacterial agent for Acute Otitis Media stated as below:
1) To identify any history of acute onset, evaluation of signs and symptoms of middle ear inflammation, and signs of middle ear effusion.
2 ) Assessment of pain to recommend any antibacterial agent.
3) Prescription of amoxicillin (antibacterial agent) for most children whose dose should be 80
to 90 mg/kg per day.
4) Selection of different initial antibiotic a temperature greater than or equal to 39 degree Celsius other than amoxicillin .
Answer:
I believe the answer is Rectus abdominis
Explanation:
The rectus abdominis muscles are a pair of long muscles that run vertically up the front of the abdomen, stretching from the pubis to the xiphoid process. They compress the viscera and tense the abdominal wall.
