Studies have shown that, although there are significant differences in the amounts of tissue different surgeons remove when excising lesions of similar size within a single unit, the variations are small.

Example(s): The study in Box 1 has not been subject to a formal sample size calculation due to a lack of available data on the magnitude of the various components of variation planned into the design (e.g., the variation in flow rates between time-points in a particular experiment on a particular unit, the variation between experiments, and the variation between units).
The multiplicity of identified homology units, the variation in replicon number and the modifications of homology unit content during and after replication suggest the evolutionary development of the bovine TRAV/TRDV repertoire has been highly complex.
As all hospitals in the current study had short-stay wards or medical observation/assessment units, the variation in proportion of medical admissions between hospitals cannot be attributed to the availability of short-stay wards.
The amide region (7.8 9.4 ppm) of each 1D N-edited spectrum was integrated as a single unit and the variation in the resulting intensity (I) with squared gradient strength (G) fit to a single exponential decay of the form, I = I0 exp −dG), to extract a diffusion decay rate (d) which is linearly proportional to the translational diffusion coefficient of the protein.
The samples need to be taken in spatial units where the variation of the conditions potentially influencing the infection can be neglected.
The model can be used for the simulation of operational strategies, thus representing a versatile and important tool for the implementation of advanced management such as the installation of local storage units or the variation of user request schedules.
The degree of bias introduced into the actuarial estimate by differential loss to follow-up was small, in the range of 1.2 2.9% units, and the variation by age was somewhat less than indicated by the actuarial estimates.
When the OR is equal to 1, the effect of the unit variation of the regressor on the dependent variable is null.
We then calculated for each unit the coefficient of variation (CV) of the MFR for each segment size.
Specifically, (3) r s = γ 0 + γ e tan θ, where γ0 is a parameter that is initially set to the r.m.s.d. of the Ewald offset calculated for all the reflections on a given image, γ e represents the width of the energy spread and the unit-cell variation (the initial value of γ e is calculated from the average energy spread), and θ is the Bragg angle.

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
