Epidemiological studies suggest considerable overlap between functional dyspepsia (FD) and irritable bowel syndrome (IBS).
Eleven patients were diagnosed by their neurologists as having neuromyotonia only, but four of these had pain, autonomic dysfunction or insomnia, features that could be ascribed to Morvan's syndrome, suggesting considerable overlap between the two syndromes.
The beta coefficient was high (α = 0.88), with the upper limit of the confidence interval approaching 1 (upper CI = 0.99), again suggesting considerable overlap of liabilities for initiation and progression.
Preliminary regression analyses showed collinearity between the indicators exploring national public expenditure on health care and national per capita health expenditure, suggesting considerable overlap between the two measures in terms of their relationship with maternal mortality.
These molecules are also markers of proposed stem cells from other epithelial tissues including prostate (Sca1+; Xin et al, 2005) and CD45−; Lawson et al, 2007) and skin (CD34+; Blanpain et al, 2004), again suggesting considerable overlap between stem cells from different organs.
Longitudinal, epidemiological studies of cigarette and marijuana use in adolescents in a US-based sample also suggest considerable overlap in risk factors (e.g. peer substance use and other substance use) for the initiation and progression stages, with only a few stage-specific risk factors found [ 37, 38].
Studies that have compared locally-developed, emic mental health measures to globally-deployed, etic measures suggest considerable psychometric overlap between instruments, but highlight that local development does provide some additional value in terms of both content and external validity [ 12, 21].
This suggests considerable potential for residual confounding.
It may be appropriate to include those with challenging behaviour because it is suggested that there is considerable overlap between mental health problems and challenging behaviour.
Indeed, the application of induced sputum to study large groups of patients with airway disease has suggested that there is considerable overlap between these conditions, with neutrophilic inflammation observed in up to 40% of patients with asthma, particularly in those with severe disease.
Collectively, these findings suggest that there is considerable overlap in the biogenesis of LBs and melanosomes.
