■国家研究指导网络（NRMN）是美国国立卫生研究院资助的多元化科学计划，技术,工程,数学,和医学研究人员通过提供指导，网络,和专业发展资源。NRMN通过其在线平台MyNRMN为会员提供指导资源。
■MyNRMN帮助会员建立导师网络。我们的目标是扩大招生和指导联系，尤其是那些历来在生物医学培训和生物医学劳动力中代表性不足的人。
■为了提高注册的便利性，我们实现了平台注册用户界面迭代的分割测试。为了增加指导联系，我们开发了多种功能，便于通过不同的途径连接。
■我们改进的用户界面产生了更高的完成注册率（P<.001）。我们的分析表明，与使用传统表格的注册相比，使用版本1表格的注册人数有所改善（赔率比1.52，95％CI1.30-1.78）。版本2表格，随着它的简化，1步流程和较少的必填字段，优于传统形式(赔率比2.18，95%CI1.90-2.50)。通过改进招生表格，MyNRMN注册完成率从旧版表格的57.3%(784/1368)增加到版本2表格的74.5%(2016/2706).我们新开发的功能增加了成员之间的联系。
■我们的技术努力扩大了MyNRMN的会员基础，并增加了会员之间的联系。其他平台开发团队可以从这些努力中学习，以增加代表性不足的群体的入学率，并促进持续，成功参与。
UNASSIGNED: The National Research Mentoring Network (NRMN) is a National Institutes of Health-funded program for diversifying the science, technology, engineering, math, and medicine research workforce through the provision of mentoring, networking, and professional development resources. The NRMN provides mentoring resources to members through its online platform-MyNRMN.
UNASSIGNED: MyNRMN helps members build a network of mentors. Our goal was to expand enrollment and mentoring connections, especially among those who have been historically underrepresented in biomedical training and the biomedical workforce.
UNASSIGNED: To improve the ease of enrollment, we implemented the split testing of iterations of our user interface for platform registration. To increase mentoring connections, we developed multiple features that facilitate connecting via different pathways.
UNASSIGNED: Our improved user interface yielded significantly higher rates of completed registrations (P<.001). Our analysis showed improvement in completed enrollments that used the version 1 form when compared to those that used the legacy form (odds ratio 1.52, 95% CI 1.30-1.78). The version 2 form, with its simplified, 1-step process and fewer required fields, outperformed the legacy form (odds ratio 2.18, 95% CI 1.90-2.50). By improving the enrollment form, the rate of MyNRMN enrollment completion increased from 57.3% (784/1368) with the legacy form to 74.5% (2016/2706) with the version 2 form. Our newly developed features delivered an increase in connections between members.
UNASSIGNED: Our technical efforts expanded MyNRMN\'s membership base and increased connections between members. Other platform development teams can learn from these efforts to increase enrollment among underrepresented groups and foster continuing, successful engagement.
