We showed that the precision obtainable with a given budget depends greatly on the surveillance levels at which the estimation strategy is focused, and that pyramidal estimators with 3 surveillance levels can dramatically decrease the necessary budget in comparison with follow-up of a series of symptomatic cases.
Similarly, if one treatment group had an event rate of 50%, an event rate of at least 72% would have been necessary in the comparison treatment group.
Therefore, the left lateralized activation for parity judgement may reflect additional retrieval of parity information not primarily necessary in magnitude comparison.
For example, if one treatment group had an event rate of 1%, an event rate of at least 11% would have been necessary in the comparison treatment group to allow at least an 80% chance of detecting a statistically significant difference between the two treatment groups.
Caution is necessary in these comparisons, as the addition or removal of parameters is likely to be accompanied by a change in the underlying non-linear logic of the simulation that can turn sloppy and stiff parameters into their respective opposite.
27 Therefore, we would argue, the intuitive appeal of this line of argument comes from underlying assumptions about the likelihood of whether the future rescue will be either necessary or effected, in comparison to the relative certitude and necessity of saving someone in need today.
To that end, longitudinal follow-up studies associated to the AMRSID method are necessary, in which the comparison of the MR signal distribution patterns will allow the definition of predictive factors of scoliosis progression using contingency tables, relative risk and percentage attributable risk factors.
The time and memory necessary are greatly reduced in comparison with the classical finite element method.
It has been previously reported that for the comparison of measurement methods, at least 53 paired-values for hemoglobin were necessary in operating theaters [20], whereas 127 202 consecutive paired analyses were necessary for comparison in ICUs where higher variability is expected [21, 22].
