## Simulated Observational Study

### Description

Datasets were simulated using baseline covariates (sampling with replacement) from the Effects of Aspirin in Gestation and Reproduction (EAGeR) study.
Data generating mechanisms were described in our manuscript (Zhong et al. (inpreparation), Am. J. Epidemiol.).
True marginal causal effects on risk difference, log risk ratio and log odds ratio scales were attached to the dataset attributes (true_rd, true_logrr,true_logor).

### Usage

```

### Format

An object of class data.frame with 200 rows and 8 column:

- sim_Y
binary, simulated outcome which is condition on all other covariates in the dataset

- sim_A
binary, simulated exposure which is conditon on all other covarites expect sim_Y.

- eligibility
binary, indicator of the eligibility stratum

- loss_num
count, number of prior pregnancy losses

- age
continuous, age in years

- time_try_pregnant
count, months of conception attempts prior to randomization
