Replication Data for: Increasing water availability during afterschool snack: evidence, strategies, and partnerships from a group randomized trial

This site-level (n=20) data set was created in order to analyze whether the OSNAP intervention resulted in increases in the volume of water served from baseline to follow-up. It covers both baseline and follow-up data for the main OSNAP trial. It contains information on the average daily volume of different types of beverages (water, 100% juice, SSBs, milk) served during snack at baseline and follow-up, as well as the frequencies with which these beverages were served and the average calories served from beverages; it also contains site-level demographic information and matched pair variables.本站点层面（n=20）数据集专为分析OSNAP干预是否可使随访阶段相较于基线阶段的供水量提升而构建。该数据集涵盖了OSNAP核心试验的基线与随访阶段全部数据，包含基线及随访阶段茶点时段供应的各类饮品（饮用水、100%纯果汁、含糖饮料（Sugary-Sweetened Beverages，SSBs）、牛奶）的日均供应量、供应频次，以及饮品供应的平均热量；同时还包含站点层面人口统计学信息与匹配对变量。
