The term "validated formula" is correct and usable in written English.
It is usually used to refer to a formula that has been tested and confirmed to be accurate. For example, the researchers used a validated formula to calculate the average cost of services.
With an accuracy of 81.6% and a low false-negative rate, we established a reliable prospectively validated formula assessed by one simple blood collection selecting 'high risk' patients being vulnerable for severe hyperkalemia.
20 Doppler assessment of AS included measurement of peak and mean transvalvular velocities and gradients; aortic valve area by the continuity equation, indexed for body surface area; and pressure recovery adjusted aortic valve area (ie, energy loss index (ELI)) calculated by a previously validated formula.
With this validated formula, further dissection of the bearing mechanism of PBL shear connectors was carried out.
A validated formula was used to determine LV mass.
Capillary HbA1c was converted to venous values using a validated formula [ 12].
LVM was calculated using an anatomically validated formula for echocardiography [ 26, 27] and did not include the papillary muscles.
GFR was calculated using the cystatin-C values and validated formulas [ 27].
Pulmonary blood flow was calculated using standard validated formulas incorporated in the Innocor® software [ 12, 13].
Validated formulas appropriate for assessment of fat-free mass (FFM) and skeletal muscle mass (SMM) in the elderly were used as suggested by Duerenberg et al. [ 62].
Aortic distensibility will be assessed at the ascending aorta and proximal descending aorta at the level of the pulmonary artery and the distal descending aorta at the level of the diaphragm on held end-expiration and calculated using previously validated formulae.
We only assessed the statistical uncertainty of the suggested spatial associations tentatively; developing and validating formulas for the standard error is an issue that also deserves further attention.
