Multidimensional integrative data analysis of digital phenotyping is crucial for elucidating the pathologies of multifactorial and heterogeneous diseases, such as the dry eye (DE). This crowdsourced cross-sectional study explored a novel smartphone-based digital phenotyping strategy to stratify and visualize the heterogenous DE symptoms into distinct subgroups. Multidimensional integrative data were collected from 3,593 participants between November 2016 and September 2019. Dimension reduction via Uniform Manifold Approximation and Projection stratified the collected data into seven clusters of symptomatic DE. Symptom profiles and risk factors in each cluster were identified by hierarchical heatmaps and multivariate logistic regressions. Stratified DE subgroups were visualized by chord diagrams, co-occurrence networks, and Circos plot analyses to improve interpretability. Maximum blink interval was reduced in clusters 1, 2, and 5 compared to non-symptomatic DE. Clusters 1 and 5 had severe DE symptoms. A data-driven multidimensional analysis with digital phenotyping may establish predictive, preventive, personalized, and participatory medicine.
数字表型的多维综合数据分析对于阐明多因素和异质性疾病(如干眼症)的病理机制至关重要。这项众包横断面研究探索了一种基于智能手机的新型数字表型策略,以将异质性干眼症症状分层并可视化成不同的亚组。2016年11月至2019年9月期间从3593名参与者收集了多维综合数据。通过均匀流形逼近和投影进行降维,将收集到的数据分层为有症状干眼症的七个聚类。通过层次热图和多变量逻辑回归确定每个聚类中的症状特征和风险因素。通过弦图、共现网络和Circos图分析对分层的干眼症亚组进行可视化,以提高可解释性。与无症状干眼症相比,聚类1、2和5中的最大眨眼间隔缩短。聚类1和5有严重的干眼症症状。基于数据驱动的数字表型多维分析可能建立预测性、预防性、个性化和参与性医学。
