We introduce the sdid command, which implements these methods in Stata, and provide several examples of use, discussing estimation, inference, and visualization of results. Along with SDID, the sdid command allows for the implementation of standard synthetic control and difference-in-differences ...

This Stata package implements the synthetic difference-in-differences estimation procedure, along with a range of inference and graphing procedures, following Arkhangelsky et al., (2021). Arkhangelsky et al. provide a code implementation in R, with accompanying materials here:synthdid. Here we provi...

SMD was selected as given our large sample size, small clinically unimportant differences, are likely to be statistically different when using t-tests or chi squared test. A SMD greater than 0.1 is deemed as a potentially clinically important difference, a threshold often recommended for declaring ...
size, small clinically unimportant differences, are likely to be statistically different when using t-tests or chi squared test. A SMD greater than 0.1 is deemed as a potentially clinically important difference, a threshold often recommended for declaring imbalance in pharmacoepidemiologic research [97...
Due to the limited literature regarding the impact of Pistacia atlantica on antioxidant capacity in humans and citing the expert’s opinion, the effect size [standardized mean difference (SMD)] was considered to be at least one. Based on this, considering the first type error of 5% and power...
this randomized clinical trial that included 160 patients with rheumatoid arthritis in remission taking csDMARD therapy, treatment with half-dose vs stable-dose csDMARDs resulted in disease flares in 25% vs 6% over 12 months; this did not meet the noninferiority criterion of a 20% difference. ...
