A Texas law aimed at restricting abortions that took effect in 2013 has led to more women trying to end a pregnancy on their own, while the number of clinical procedures in the state has declined, according to a study released on Tuesday.

The study showed that poor women bear the brunt of the law.

"Poverty, limited resources, and local facility closures limited women's ability to obtain abortion care in a clinic setting and were key factors in deciding to attempt abortion self-induction," the Texas Policy Evaluation Project found.
