For the more commonly used SPECT isotopes like 201Tl, 99mTc and 111In, misalignments up to a few millimetres or in the order of 10° to 15° between micro-SPECT and micro-CT, and/or global attenuation coefficient inaccuracies in the range of ±10% have quite small effects on micro-SPECT quantification.
Linkage studies followed by positional cloning identified six genes while association studies identified over a hundred genes, the majority of these having quite small effects on asthma susceptibility (see [9], [10] for a review).
The approaches described above can be applied to identify genes for heading date QTLs with quite small effects, such as those detected in this study.
Unless the air is of a very significant volume, it seems likely that it has quite small effects after a few hours or a day or two; hence my suspicion this case is more a PDPH than PC headache.
Despite the magnitude of the ripples is quite small, the effect is still responsible for the unusual transport behavior of graphene, also susceptible to adsorbed impurities, defects, and the roughness of the underlying substrate [40 43].
Overall, the actually observed deviations of SUR from the regression line in Figure 4B directly reflect the (quite small) cumulative effect of both V r and input function shape variability in this patient group.
"The claim that caffeine affects the consolidation of memories is based on quite a small effect that would really benefit from replication in a larger sample to be convincing," he said.
This is especially the case for the post hoc analysis of IGA-RSS for the proportion of participants with complete resolution, which although it favours the active treatment, could be consistent with quite a small effect.
Fine control for socioeconomic factors at the block group level, which in urban areas is quite small, had little effect on associations with PM2.5.
Since the vegetative stage is quite long, small effects early in the vegetative stage could result in a large effect over the course of one social generation [ 20].
