A correlational relationship simply says that two things perform in a synchronized manner.For instance, there has often been talk of a relationship between ability in math and proficiency in music.The C stratigraphic records are compatible with volcanically induced global environmental change that could be the proximal cause of extinction.The revised Early Jurassic time scale suggests that peak extinction in the early Toarcian occurred at 183 Ma.This compilation suggests that the end of the Triassic Period (ca.200 Ma) coincided with peak volcanism in the Central Atlantic magmatic province and that terrestrial floral and faunal extinctions may have slightly preceded the marine biotic crisis.Or, does it mean that if we don't have enough roads in Europe, we should encourage U. When the economy is good more roads are built in Europe and more children are born in the U. The key lesson here is that you have to be careful when you interpret correlations.
Aim: The purpose of this study was to determine the post-traumatic interval of Subdural Haemorrhage (SDH) based on Hounsfield Unit measurements (HU) on Computed Tomography (CT) in surviving victims of head injury.A 4-year multi-centre observational study of 302 cases.Chronic subdural haematoma (CSDH) is a common neurosurgical condition and is more prevalent in the ageing population.Conclusion: The density of the subdural haematoma decreases with increase in the post-traumatic interval that concurs with the limited number of studies being conducted in the past.We concluded that further sorting of cases could be done according to its age with additional research and uniformity in the methodology. Although carefully collected, accuracy cannot be guaranteed. Differing provisions from the publisher's actual policy or licence agreement may be applicable.
