Explanation
A CD4 count of 180 cells per cubic meter is considered very low - typically an indicator that the patient has an immunocompromised state, such as AIDS. CD4 counts are a measure of healthy T-cell levels. The lower the count, the more susceptible the patient is to opportunistic infections. A normal range is between 500 and 1,500 cells.

Explanation
Odds ratio of 0.44 (44%) means that this group was associated with an event happening 44% of the time, compared to 1 (an event happening 100% of the time if unexposed), therefore 100 - 44 = 56%, which is the reduction caused by the exposure. Exposure is the use of ascorbic acid.

15% dextrose = 15gm/100ml = 300gm/2000ml. Patient needs 300gm. 300gm/Xml = 20gm/100ml = 1500ml

LDL can be elevated by diuretics, cyclosporine, glucocorticoids, and amiodarone.

Explanation
The following NSAIDs belong to the propionic acid derivatives group - Ibuprofen - Ketoprofen - Naproxen - Fenoprofen - Flurbiprofen - Oxaprozin whereas piroxicam belongs to the class of Enolic acid derivative which also includes other agents like meloxicam and Nabumetone. They are non-selective COX inhibitors and act by preventing the production of certain prostaglandins.
