International Law Systematic Review Dataset v1.0

Index, and Worldwide Political Science Abstracts. The study selection included publicly available peer-reviewed studies and gray literature (e.g., dissertations) that aimed to quantitatively measure an international treaty’s effect on any objective and quantifiable outcome. Further details on the review of titles and abstracts for eligibility, final consensus for inclusion, aggregation and deduplication using EndNote, and assessment for bias using Cochrane’s ROBINS-I tool are found in SI Appendix.

This dataset contains information on treaty characteristics from 199 unique quantitative estimates evaluating 53 unique treaties. At the time of study inception, there was no existing systematic field-wide evidence synthesis that could provide the information upon which to evaluate the effects of international treaties.
