Univariate and multivariate analyses revealed that tumours with high positive expression for SOX2 were significantly associated with a recurrence event, with a 4.7-fold higher risk, compared with tumours with low expression for SOX2 (Supplementary Table S1B).
Carotid plaque was also significantly associated with cardiovascular events: the multivariate RRs with 1 unit increment in carotid plaque were 1.15 (95% CI, 1.07 1.24) for CHD and 1.11 (95% CI, 1.05 1.18) for stroke events.
There is no method described in the literature for an exact power calculation for multivariate statistical methods with event times as the endpoint and equivalence as the main question of the analysis.
The answer to the second question concerning the difference between the risk assessment groups will probably be answered since the sample size was calculated rather generously due to lack of an exact power calculation for multivariate statistical methods with event times as the endpoint and equivalence as the main question of the analysis (see above).
The second approach is based on multivariate analysis techniques that probe the compatibility of the candidate events with the signal.
We used Cox regression models for survival without the event (dialysis/death) with both univariate or multivariate analyses (with different covariates: categorical or dichotomous or continuous).
It is worth noting that combined use of multivariate data (i.e., seismic, geodetic, tsunami, and so on) possibly compensates for the weakness of single variable data analysis during great events with complex disasters.

Including 5 variables in a multivariate model with roughly 60 patients and 30 events is, however, a stretch.
Our screening method, based on cellular imaging cytometry, provides simultaneous monitoring of cellular events and facilitates quantitative multivariate cellular analysis with the elimination of false positive errors, as it provides high-spectral resolution among the fluorophores.
