We assessed the prevalence of overactive bladder in a population-based study of subjects of both sexes aged 18 79 years.
In a large population-based survey, PFOA but not PFOS was associated with both transaminase and GGT levels (Lin et al. 2010), although those findings differed from those of an earlier, much smaller population-based study of subjects heavily exposed to PFOA (Emmett et al. 2006).
The Irish Longitudinal study on Ageing (TILDA) is a population-based study of subjects aged 50 years or older, designed to investigate factors that influence ageing, and has enabled this investigation of the prevalence of AMD in the Republic of Ireland (ROI).
Larger community based studies that use probability sampling of subjects are required to substantiate our findings.
A population based study of 11876 diabetics included 923 subjects with a cancer.
While studying a population based cohort of subjects we observed that the FLG defects conferred an increased risk for development of AD, AR (in particular pAR) and asthma (in particular AA).
According to three large studies based on thousands of subjects from UK and Denmark, it can be concluded that long-term exposure to lithium is associated with increased rates of CKD (Close et al. 2014; Kessing et al. 2015; Hayes et al. 2016).
Prospective techniques are one potential solution; such studies, based on cohorts of subjects identified before the onset of disease and before the exposures under investigation (e.g., at or before birth) and followed across the life course, have become key to investigations of early developmental events in schizophrenia.
A study that included a community based population of subjects with chronic shoulder pain, found that the relation between pain and psychological health was dependent of level of disability [ 9].
Divergent results in a meta-analysis often lead investigators to draw conclusions based on subgroups of subjects or studies.
A small increase of approximately 40% in the risk of childhood cancer is thought to be detectable for acute exposure to diagnostic in utero radiation at doses in the range of 10 mGy, based on results from case control studies of subjects born between late 1940s and early 1980s (Doll and Wakeford, 1997).
