Cohorts with and without CS were constituted, matched on the propensity scores (3-to-1 matching: population of early survivors, 94 patients with CS, 282 patients without CS; population of 1-year survivors, 73 patients with CS, 217 patients without CS), and their outcomes were compared using log-rank tests.
This study was designed to compare the long-term outcomes of patients with peripheral arterial disease (PAD) with a risk factor matched population of coronary artery disease (CAD) patients, but without PAD.
In recent studies mental health outcome of donors have been compared to a matched population of healthy individuals.
Only 1,381 of the 6,752 (20.5%) patients could be matched to a nonadmitted patient, resulting in a matched population of 2,762 patients.
When compared with the global population [ 6] and the subgroup with multiple organ failure [ 7] of PROWESS, the 840 patients in the matched population of PREMISS had different baseline characteristics.
Comparison of the survival data from our study with that of a matched population of patients with suboptimally debulked, advanced ovarian cancer, all of whom received between five and eight cycles of carboplatin (Lambert et al, 1993, 1997), were identical.
Therefore we conclude that average heterozygosity is only useful for ignoring the effect of certain SNPs when estimated from a closely matched population of individuals to the cell being studied.
The main objective of this project is to compare direct health care utilization and costs for pain management in individuals with COPD to a matched population of patients with other chronic diseases.
In a previous study [ 15], we found that in a FEV1% matched population of COPD patients, women had worse SGRQ scores than men at younger age and earlier stage of the disease.
To assess the contribution of polyploidy to tumorigenicity, we obtained sorted, matched populations of diploid and polyploid cells expressing equivalent levels of the Pim-1 protein.
For each sensor, the signtest assessed whether the medians of the two matched populations of controls and patients (assumed to have arbitrary and continuous distributions) were different or not.
