Body weight variability was assessed using four indices, including variability independent of the mean (VIM). A multivariate-adjusted Cox proportional hazards regression analysis was performed. Results: During a
The incidence of ISR and its relationship with visit-to-visit HbA1c variability, expressed as coefficient of variation (CV), standard deviation (SD) and variability independent of the mean (VIM), were studied. Multivariable Cox proportional hazards models were constructed to analyze the predictive ...
Hemoglobin variability was defined as the variability in measured hemoglobin levels for independent measurements of health screenings. The 3 indicators of hemoglobin variability were used: coefficient of variation (CV), standard deviation (SD), and variability independent of the mean (VIM). CV was ca...
China. Variability independent of the mean BP (VIM) obtained by 44-h ambulatory BP monitoring was used to calculate BPV. Baseline characteristics, physical measurement, and laboratory parameters were compared between different groups categorized by quartiles of VIM ...
Four continuous lines represent the risk independently associated with blood pressure variability independent of the mean (VIM) equal to 3, 6, 9, and 12 units. P-values are for the independent effect of SBP (PSBP) and VIM (PVIM). np and ne indicate the number of participants at risk ...
Intra-individual bodyweight variability between visits was calculated using variability independent of the mean (VIM). VIM is a measure of variability designed not to correlate with mean levels and is calculated as SD/meanχ, where χ is derived from fitting curves by nonlinear regression analysis ...
J-HOP study (Japan Morning Surge-Home Blood Pressure) participants underwent home BP monitoring in the morning and evening for a 14-day period, and their BP levels and BP variability independent of the mean (VIM) were assessed. Incident CVD events included coronary heart disease and stroke. ...
Moreover, multiple indices for measuring lipid variability exist (e.g., standard deviation [SD], coefficients of variation [CV], variability independent of mean [VIM], and average real variability [ARV]), but little is known about the comparative predictive performance of these indices for ...
Other methods suggested to calculate variation independent of the mean (VIM), average real variability (ARV), or average successive variability (ASV), which is the average absolute difference between successive values. VIM was defined as the SD divided by the mean to the power x and multiplied ...
25, 26 (3) Variance independent of mean (VIM) expressed as standard deviation/meanx, where x is derived experimentally such that the absolute value of the correlation between VIM and mean is minimum. VIM was chosen in order to compare our findings to previously published reports of the ...
