What is the first step of a propensity score analysis (according to Austin, 2011)?
*
specify the propensity score model to estimate propensity scores
match treated and untreated subjects on the estimated propensity scores
compare the similarity of baseline characteristics between treated and untreated subjects in a the propensity scorematched sample
estimate the effect of treatment on outcomes using propensity scorematched sample
How did Austin (2011) estimate the propensity score?
*
He used a logistic regression model, where the treatment status was regressed on 33 baseline characteristics.
He used a Cox proportional hazard model, where the outcome status was regressed on 33 baseline characteristics.
He fitted a modified the Cox proportional hazards model by using restricted cubic smoothing splines to model the relationship between continuous baseline covariates and the loghazard of mortality.
In Table 1 of Austin (2011), what balance diagnostic was used to compare the baseline characteristics of treated and untreated participants?
*
Standardized Difference of the Mean
logistic regression model
area under the receiver operating characteristic [ROC] curve
number needed to treat (NNT)
Which of the following approach is not a direct propensity score analysis technique?
*
Inverse Probability of Treatment Weighting
Propensity Score Matching
Covariate adjustment using the propensity score
McNemar's test
Stratification on the Propensity Score
