Most of the studies were descriptive in nature and were not designed as true prognosis studies.
An up to date population-based study could make an important contribution to our current knowledge of sudden and severe headache, specifically the true incidence and prognosis of vasoconstriction syndromes, and better assessment of the clinical features and prognosis of those with 'uncertain' or 'unclassifiable' headaches.
As a consequence, the true incidence and prognosis of new-onset AF in patients presenting with sepsis remains unknown.
Thus, even though this complication might possibly self-heal after complete absorption of the foreign material, we strongly advice against nonsurgical management, which would surely worsen the prognosis of a true, more common postoperative infection.
In the presence of a true, direct toxic effect upon prognosis of elevated blood glucose, failure to correct hyperglycaemia may represent suboptimal clinical care, and patients without known diabetes may be particularly disadvantaged.
Therefore, these data are thought to be more reflective of the true overall prognosis given the current management of sarcoma across the NCDB contributing sites.
In the test set, this validation showed an accuracy of 92.3%, sensitivity of 85.57% (true-poor prognosis rate) and specificity of 100% (true-fair prognosis rate) for all the left out samples (test samples).
Additional prospective, randomized controlled trials are needed to identify the true significance of TUBB3 and ERCC1 in the prognosis of gastric cancer.
16 different scenarios were identified which differed by the proportion of patients switching, underlying prognosis of switchers and the size of true treatment effect.
Furthermore, by not selecting out certain patients for inclusion or exclusion as has frequently been done in previously reported series, such as selecting only patients undergoing attempts at curative resection, these data are thought to be more reflective of the true overall prognosis for unselected patients following diagnosis.
