In a box and whisker plot: the ends of the box are the upper and lower quartiles, so the box spans the interquartile range; the median is marked by a vertical line inside the box; the whiskers are the two lines outside the box that extend to the highest and lowest observations. Example 1 â Box and whisker plots Summary A box and whisker plot (sometimes called a boxplot) is a graph that presents information from a five-number summary. It does not show a distribution in as much detail as a stem and leaf plot or histogram does, but is especially useful for indicating whether a distribution is skewed and whether there are potential unusual observations in the data set.
Causes and Risk Factors for Henoch-Schonlein Purpura. The exact cause of HSP is not known. The body's immune system is believed to play a role in targeting the blood vessels involved. An abnormal immune response to an infection may be a factor in many cases.
Cortisol breaks down muscle tissue and can be overactive during periods of elevated stress (e.g. over-training, diet, emotional stress). Cortisol causes muscle tissue breakdown through the activation of UPP (23). Researchers have discovered a few other mechanisms which trigger the UPP pathway.eople with excess thyroid production are often in a catabolic state as excess thyroid hormone can cause muscle protein breakdown mainly mediated by increasing UPP activity (21). Additionally, low level of plasma insulin triggers protein breakdown in muscle through activation of the UPP (6, 7).
