The analyses in the positive reports have involved few osteoporotic fractures, and no consistent dose-response pattern has been detected. This form usually includes 6 parts: 1) abstract (a summary of the article) 2) introduction (a brief review of why they chose this experiment) 3) materials and methods (what organisms and equipment were used) if(!e)return true; var e=document.getElementById(a); a.

Here is a short example: The particular experiment has been carried out in order to define the factors that have a positi… Make sure that it doesn't exceed more than 10 words. In one sentence, state the hypothesis. The final paragraph starts off with a literature review telling us what sorts of previous studies have been performed on this topic.

The last sentence then gives us the purpose of the current study. Thus, it is uncertain whether, to what extent, and at what level physical activity influences the risk of osteoporotic fractures in men.
