Propensity score matching is a tool for causal inference in non-randomized studies that allows for conditioning on large sets of covariates.The use of propensity scores in the social sciences is currently experiencing a tremendous increase;however it is far from a commonly ...
EMP_rate, which is a regional indicator reporting the percentage of workers over the population aged 15 and more, is positive and highly significant, meaning that the higher the rate of workers in a specific region, the higher the number of people with VHI in that region. Educational level ...
I estimate models with bandwidths between 0.1 and 0.11, meaning that for a given student who reports encouragement the comparison match is derived from comparison students whose propensity score fell within 0.05 and 0.055 on either side of the score of the student who reported encouragement. This ...
Findings: Compared with transversus plane block, intrathecal hydromorphone improved postoperative pain relief during movement.Meaning: Intrathecal hydromorphone could be an effective option for patients underwent upper abdominal surgeries.Huang, Yue-xin
Specifically, all four types of PSM methods confirm a significant difference in the potential outcome variables—meaning that a child born with LBW has a significant adverse effect on the potential child health outcome variables (stunting, wasting and both). Thus, the propensity score matching ...
The first test is done to check the assumption of common support, meaning that we check whether we have an overlap in the distribution of propensity scores among the treatment and control groups (Garrido et al., 2014). This assumption is tested by graphing the propensity scores of each group...
Nearest Neighbour (NN) propensity score (PS) matching methods are commonly used in pharmacoepidemiology to estimate treatment response using observational data. Unfortunately, there is limited evidence on the optimal approach for accurately estimating bi
The estimation results obtained for the explanatory variables in the logit model have little substantive meaning and can therefore safely be omitted, and the significance of the explanatory variables does not need to be focused on, because the estimated coefficients of explanatory variables are likely ...
The matching rate was unknown and as in most other trials most likely less than 100%, meaning that recruit- ing just the same number of patients as in the external control arm will not result in a situation where a match- ing partner is found for all patients in the control group. A ...
This question is relevant against the background of broad evidence regarding the meaning of intelligence for numerous factors of life quality such as educational success, employment status, higher income, better health, higher life expectancy, and enduring partnerships (Der et al., 2009, Gottfredson,...
