We tested the number of per week device conversion process away from levonorgestrel disaster contraceptive in the usa per 1000 female aged fifteen-44. I reviewed these types of each week transformation data that with a keen autoregressive provided moving average (ARIMA) regression to determine whether or not merchandising conversion out of levonorgestrel emergency contraceptive somewhat enhanced within the examined vacation attacks.

The fresh new ARIMA modeling process consists of three iterative steps: identity, estimation, and diagnostic examining.47 In accordance with the possible ARIMA patterns identified regarding study of the fresh new autocorrelation and you will limited autocorrelation features, model gang of an optimum design is normally predicated on minimizing Akaike pointers standards and you will Schwartz bayesian traditional. The new chose design we projected is an ARIMA(step 1,1,1). Although we chosen the potential design one lessened this type of requirements, new claimed results are sturdy in order to design specs away from autoregressive and you can swinging mediocre purchase among you’ll patterns.
To test changes in conversion process equal to the vacation periods, we integrated dichotomous covariates regarding the selected ARIMA design. I aesthetically and you will statistically inspected the fresh residuals for the last model to help you confirm that they was generally speaking distributed in place of autocorrelation.forty eight We made use of Stata 17.0 for all screening. We made use of the STROBE cross-sectional number whenever writing the declaration.forty two

Despite its popular nickname because the “day after tablet,” levonorgestrel crisis contraceptive works well whenever taken in this 96, and maybe 120, occasions just after exposed intercourse.42 For people who had unprotected genital intercourse from inside the The fresh new Year’s Eve getaway, disaster birth control consumed the changing times quickly thereafter you certainly will efficiently stop an unwanted pregnancy.

Because these vacations slide towards the Vacations (your day finish per week conversion choices), we used the few days after the these holidays. The full directory of dates by classified holiday is available in additional desk B.
