However, these relationships were not absolute as we found examples of mutants with moderate aggregation propensity in which disease duration is shorter than 10 years: I113T and L144F see1 (Supplementarytary Material, Table S1, Fig. 5).

Depending on the degree of bias, another approach is to perform propensity score analyses, in which the treatment groups are combined, and a logistic regression predicting original group membership from covariates performed.
Where randomization is not possible, matching techniques, such as propensity score matching in which two groups of households with similar observable characteristics (household demographics, assets, income sources), can be used.
In a propensity-matched sample in which all covariates achieved balance, receipt of rhAPC was associated with reduced hospital mortality (40.7% vs. 46.6%; risk ratio, 0.87; 95% confidence interval, 0.80 to 0.95).
This involved using the propensity score stratification approach, in which the final model (excluding the propensity score) was re-estimated separately within strata based on the propensity score.
We used two approaches, namely, the creation of matched pairs based on propensity score and logistic regression analysis of outcomes in which propensity score participated as a variable.
Other methods in this setting include propensity score adjusted models in which the probability of treatment assignment conditional on baseline covariates (or propensity score) is adjusted for as an additional covariate.
Of note, two of the propensity scores used (for both outcomes) included an important pair in which one propensity score was nested within a slightly larger propensity score identical to the original propensity score except for the addition of a single covariate (glaucoma diagnosis).
Table 7 demonstrates the results of the first analysis for the full and propensity score matched sample in which we test whether the German Accounting Law Modernization Act had an effect on the magnitude of absolute discretionary accruals.
Propensity quartiles represent subgroups in which the probability of receiving drotrecogin alfa (activated) was roughly constant.
This was confirmed in a propensity score-matched analysis in which patients in the treatment group who were below the therapeutic range were excluded.
