Multiple lesions from the same individual were treated as independent because the effect on the participant was not significant (logistic regression model). Details are provided in the eMethods in the Supplement. Statistical analyses used Prism, version 7.0 (GraphPad), and SAS, version 9.3 (SAS ...
Interestingly, in most cases the relative advantage of RC versus ML was determined by the relative variance rather than the bias of the estimators. Software code for all three methods in SAS is provided. Copyright 2008 John Wiley & Sons, Ltd. 展开 关键词: measurement error maximum likelihood ...

Baseline adjusted survival time was analyzed using the Cox proportional hazard model and baseline adjusted categorical data were analyzed using logistic regression. In the analysis of new T1-weighted hypointensive lesions, the missing MRI assessments were set to zero as a conservative approach, since ...
We used multivariable logistic regression adjusted for sociodemographics to determine the adjusted odds ratios (aORs) and associated 95% confidence intervals (CIs) of the subgroups of RD use for recent or established HIV infection. Results A total of 4496 Chinese MSM participated; 28.4% used RDs,...
Again, ODS TRACE is used to find the names of the objects used by PROC LOGISTIC. Figure 5 is an extract of the SAS LOG showing the 10 objects generated by PROC LOGISTIC. ODS TRACE ON; PROC LOGISTIC DATA=mydata DESCENDING; CLASS DaysMix (PARAM=REF REF="None"); MODEL asthma = Days...
Data were analysed using the logistic procedure ofSAS. Coefficients for stalk number, height, diameter and number of eldana bored stalks were highly significant(p < 0.0001), which indicated their influence in selecting for high cane yield. Selected genotypes in BSL13 produced20% more stalks that...
Conditional logistic regression analysis, adjusting for latitude of residence at entry into the military, was used to estimate odds ratios (ORs).27 We modeled 25-hydroxyvitamin D level both as a continuous variable, to estimate its association with MS risk under a linear assumption, and in quanti...
34 Regarding the secondary objectives (MRI activity and tertiary education level attainment, defined by enrollment in at least a short-cycle higher education program), a multivariate logistic regression was used by introducing associated factors causing both the outcome and the treatment group allocation...
