Additional file 9 of Some data quality issues at ClinicalTrials.gov

Records with a primary completion date and registered with an authority in the USA. The data (5101 records from Additional file 7: Table S5) were sorted into a “USA_PriComplDate” sheet for trials registered with at least one authority in the US, and a “USA_PriComplDate_leftovers” sheet with the remaining records. The data are presented in the following six Recruitment Type categories: (1) Active, not recruiting (1085 selected records with 135 leftovers), (2) Completed (1100; 940), (3) Enrolling by invitation (19; 23), (4) Recruiting (773; 609), (5) Suspended (59; 32), and (6) Terminated (252; 74). The sheets for these categories are numbered 1–6, respectively. (XLS 493 kb)

本数据集收录带有主要完成日期且已在美国至少一家监管机构完成注册的临床试验记录。本次使用的数据集共包含5101条记录，源自附加文件7：表S5。该数据被分为两个工作表：其中「USA_PriComplDate」工作表收录了至少在美国一家监管机构完成注册的试验数据，「USA_PriComplDate_leftovers」工作表则收录剩余的未归入前者的记录。数据按以下6类招募类型进行分类统计：(1) 已启动招募但暂不招收受试者（纳入前者工作表的同类别记录共1085条，归入后者工作表的同类别剩余记录共135条）；(2) 试验已完成（对应两类工作表的记录数分别为1100条与940条）；(3) 受邀招募受试者（对应两类工作表的记录数分别为19条与23条）；(4) 正在招募受试者（对应两类工作表的记录数分别为773条与609条）；(5) 试验已暂停（对应两类工作表的记录数分别为59条与32条）；(6) 试验已终止（对应两类工作表的记录数分别为252条与74条）。上述各类别的工作表分别编号为1至6。本数据集为XLS格式文件，大小为493 KB。
