Possible explanations for the weaker association seen in the study from Brazil include: this study is affected by a bias that masks a true association more than other studies; this study is less affected by a bias evident in other studies that creates a spurious or stronger association; or that this is only a random variation.
However, it is possible that if Apobec1 editing is affected by an allele carried by the A/J strain, this effect could be masked by transgressive variation or epistasis in inbred A/J animals.
The LH histogram analysis was also repeated by masking the brain area affected by the stroke in the LH of each patient, so that the histogram parameters represent only the distribution of FA values outside the lesion.
Observers were found to be primarily affected by masks of the same orientation as the test, thus suggesting that symmetry is computed separately in distinct mirror-orientation channels.
These masks were defined using anatomical CT information while sparing regions affected by high tracer accumulation in the bladder as visible in the PET image.
These results indicate that performance was not significantly affected by the mask, which presumably halts visual processing after 120 ms.
However, in the case of densely integrated devices, in which several optical waveguides are close together, interference occurs between the masks, and the characteristics of the grown waveguide layers are affected by several mask stripes.
Of the ED swabs where recovery of NTHi was not affected by masking, NTHi was cultured from a greater proportion of EDs in the PCV7 group (53 %) compared to the PHiD-CV10 group (35%%).
However, the neural processes affected by visual masking and TMS remain unclear.
Though clouds and cloud shadows were masked, several Landsat scenes were affected by haze, influencing the reflectance values in the red band.
