Sentence examples for estimation of hrs from inspiring English sources

Cox proportional hazards modeling accounting for left truncation was used for univariate and multivariate analyses with estimation of HRs and 95%% CIs.

Moreover, studies that did not report sufficient data for estimation of HRs were ruled out from this systematic review, and this might potentially generate bias.

HP used with Method 1 gave the smallest estimation of HR ¯ t.

This approach allows a focused estimation of HR reaction from traffic noise during sleep.

With Method 2 where HR ¯ t ≃ HR ¯ a t, L W A u and L W A a gave very similar values, whereas HP gave a smaller estimation of HR ¯ t than L W A u.

With Method 1, the estimation of HR ¯ t was biased with HP and L W A u, but more with HP; the estimation of HR ¯ a t was biased with L W A a. Whatever the model applied, HR ¯ t (HP, L W A u ) and HR ¯ a t (LWA a ) were underestimated, i.e. a poor prognostic exposure effect tended to be ignored and a no exposure effect tended to become a protective one.

In these three profiles, the number of events in the exposed and in the non-exposed individuals is quite low, suggesting a possible lack of accuracy in the estimation of HR ¯ t.

Note that the combination HP and Method 1, taking the exposure as a time-dependent covariate or not, gave exactly the same estimation of HR ¯ t, whereas LWA did not.

For the remaining studies, estimations of HRs and 95% CIs were attempted using the spreadsheet provided by Tierney et al (2007.

In some configurations where the proportion of the profile with the smallest HR ¯ i t was the most highly represented profile leading to a low HR ¯ t, HP was better than L W A u. L W A a was the only model for estimating H R a (t) and led to very slightly biased estimations of HR a t (data not shown).

In addition, the collection of extensive baseline information for the entire SCCS cohort, and the systematic follow up for all-cause and cause-specific mortality, enabled robust, precise estimation of multivariate HRs associated with use of statins in the largest cohort of blacks studied to date.
