- a. Shown is the odds ratio from the multivariable logistic model, with adjusted for all covariates in table (age, complication, BMI, duration of infertility, smoking status, surgical history, total number of previous, pregnancies resulting in live births, miscarriage times and treatment after HSG)
- b. Shown is the primary analysis with multivariable logistic model with the same covariates with inverse probability weighting according propensity score
- c. Shown is the odds ratio from the multivariable logistic model with the same strata and covariates with matching according to the propensity score. The analysis included 178 patients (178 undergoing HSG examination in the Oil based group and 178 in the Non-oil-based group)
