Abstract

Objectives

To assess the publication rate and time from registration to publication of systematic intervention reviews registered in PROSPERO originated from South American countries in 2020.

Study Design and Setting

Cross-sectional study. We searched PROSPERO for protocols of systematic reviews of interventions with affiliation in South America during 2020. We randomly extracted 10% and searched databases to identify their publication status.

Results

We identified 1361 intervention systematic reviews with South American affiliation registered in PROSPERO during 2020. We assessed a random sample of 10% (n = 135). The publishing rate in indexed journals was 36.9% (n = 41). The median time to publication was 1.6 years (IQR 0.9–2.1).

Conclusion

The publication rate of South American PROSPERO registers is low. These findings emphasize the need for further efforts to improve publication rates and increase the visibility of South American research in the global scientific community.

关于南美国家在 PROSPERO 登记的干预措施系统审查发表率的元流行病学研究

目的评估 2020 年在 PROSPERO 登记的南美国家系统干预综述的发表率和从登记到发表的时间。研究设计和设置横断面研究。我们在 PROSPERO 中检索了 2020 年期间隶属于南美洲的干预措施系统性综述协议。我们随机抽取了 10%，并检索数据库以确定其出版状态。结果我们确定了 2020 年期间在 PROSPERO 登记的 1361 篇与南美洲有关的干预措施系统综述。我们随机抽取了 10%（n = 135）进行评估。在索引期刊上的发表率为 36.9%（n = 41）。中位发表时间为 1.6 年（IQR 0.9-2.1）。结论南美 PROSPERO 登记册的发表率较低。这些发现强调，需要进一步努力提高发表率，提高南美研究在全球科学界的知名度。
