In order to filter out the expected background noise in the binding site density data, we multiplied each density by a sigmoidal function of the density [see Equation (3)].
As expected, background therapy in PARADIGM-HF is quite different than in SOLVD-T, with greater use of beta-blockers and MRAs, oral anticoagulants (and presumably statins, which were not available during SOLVD-T), in keeping with the accrual of new evidence of treatment effectiveness and evolution of guidelines to reflect this.
While this very low observed event rate in trials is likely to reflect a lack of systematic assessment and reporting, there is no compelling evidence to suggest that the observed event rate of psychotic symptoms in children treated with ADHD drugs exceeds the expected (background) rate in the general population.
A potential pitfall in the clinical application of PB gene expression profiling would be that variations in PB gene expression in people would be such that it might be difficult to distinguish the effects of a given exposure or medical condition from expected background alterations in gene expression [12].
The expected background signal in normal pancreas should be sufficiently low, because acinar and islet cells only showed weak positive staining in some tissues and BLT2 mRNA levels in whole pancreas are very low compared with other organs.
This is consistent with other findings and comparable to expected background rates in an elderly population: the Surveillance, Epidemiology and End Results Program reports age-adjusted incidence rates for invasive cancers of 0.6 among persons 50 54 years of age, 0.8 among persons 55 60 years of age, 1.2 among persons 60 64 years of age and 2.1 among persons 65 years of age or older.
When comparing PICRs across screening programs, differences can reflect true differences in interval cancer rates; differences in methods for estimating the expected background incidence; or differences in the time trend of breast cancer incidence.
If we assume release probabilities in the range of ∼0.1B0.3 (consistent with a binomial fit to the distribution of IPSCs observed in our voltage clamp experiments) we would obtain estimates of the expected background rate of uIPSCs in the range of 100B600 Hz, or less if some of the release sites were in severed axons or silent somata.
In randomized controlled studies (RCTs) the expected background incidence is the incidence found in the control group.
These check for consistency in signal intensity, expected background and noise levels, mismatches versus perfect matches, and signal in housekeeping genes (Figure S1A-S1H).
