A clinical control group can be a placebo arm or it can involve an old method used to address a clinical outcome when testing a new idea. For example in a study released by the British Medical Journal, in 1995 studying the effects of strict blood pressure control versus more relaxed blood pressure control in diabetic patients, the clinical control group was the diabetic patients that did not ...

CDC technician dons an older-model positive-pressure suit before entering one of the CDC's earlier BSL-4 labs. Biosafety level 4 (BSL-4) is the highest level of biosafety precautions, and is appropriate for work with agents that could easily be aerosol-transmitted within the laboratory and cause severe to fatal disease in humans for which there ...
All group 4 subjects (except computer science and environmental systems and societies; see below) follow roughly the same format. Each subject has its Subject Specific Core (SSC), i.e., material taught at both the standard and higher levels. Students sitting the Higher Level examination study the Additional Higher Level (AHL) material.
