However, due to the cross-sectional design of the study, the direction of the correlation is unknown and causality cannot be proven.
SAEs will be classified according to intensity (mild, moderate, severe, life-threatening, death), outcome (recovered completely, recovered with sequelae, not recovered with or without therapy of SAE, death, unknown), and causality (doubtful, possibly related, probably related, definitely related, not assessable).
Several recent anti intellectual decisions has not only slowed down progress on global warming and stem cell research, it has also contributed to our current economic state and got us into an unnecessary war and occupation that has led to more than 4200 American causalities, unknown number of Iraqi deaths, at a current cost of $10 billion per month.
Factors limiting health impact quantification include: lack of data, multi-causality, unknown impacts considering a high-quality health system, complex cause-effect relations leading to multi-directional impacts, possible changes of present-day response-relations, and difficulties in predicting local climate impacts.
Variations in definitions of the environment, the health effects, and the scenarios assessed, unknown impacts of multi-causality and co-morbidity, lacking consensus about causality, controversial views about model structures, and many other sources of uncertainty may affect eBoD assessments, but cannot be easily quantified, and are usually not fully addressed.
However, whether the same or different neural processes are involved in perceiving physical and social causality is unknown.
Since this was a cross-sectional study, causality is unknown.
Given the cross-sectional, observational design of the study, the direction of causality is unknown.
It is encouraging that such practical items are indeed associated with better clinical processes, although the causality remains unknown.
However, the direction of causality remains unknown as prospective studies of cognitive function in subjects without diabetes have suggested that hippocampal dysfunction potentially causes elevated cortisol levels (22).
