They draw on several approaches to estimate the total effect, because any single study is bound to be imprecise.In this section Getting a grip Burnished An activist ousted What crisis?
Apoptosis has been discounted as causative because a single study in rats has shown that less than 2% of salivary acinar cells are apoptotic six hours following irradiation of rat salivary glands with X-rays with doses as high as 25 Gy [8].
Synthesis of the literature with such few studies was difficult because a single study may affect the outcomes.
Exposures of interest need to be prioritized, because a single study cannot measure all potentially relevant exposures.
Because a single study of this size is not sufficient to change practice, further studies are needed both to confirm the efficacy of trochanteric bursa injections in greater trochanteric pain syndrome and to determine which patients may benefit from each approach.
No, the reasons you can't jump to conclusions from this kind of study is because, inevitably, a single study can only test one aspect of the world, under one set of circumstances.
For studies that reported SMRs, we did not estimate covariance because SMRs within a single study can be assumed to be largely independent when the expected number of deaths used to calculate the SMRs is based on a sufficiently large population.
Although a number of polymorphisms have been found associated with endometriosis in selected populations, these associations have not been independently confirmed across ethnic barriers, either because only single studies are available or because other studies reported no association.
These associations, however, have not been independently confirmed across ethnic barriers either because only single studies are available or because other studies investigating these polymorphisms reported no association.
