By the central randomization system, block randomization (block size 4, 6, 8), central stratification, and BMI stratification (25< BMI<29.9, BMI≥30) were used to randomize random numbers from the experimental group to the control group in a 1:1 ratio.

From one month after the end of the study, you can contact the project leader by email (1049170817@qq.com) to apply for sharing

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

研究者在随访研究参与者后及时填写CRF,保证病例报告表上的内容与门诊或住院病历上的内容一致。病例报告表做任何更正时只能划线,旁注改后的数据,由研究者签名(签署研究者姓名的拼音缩写)并注明日期,不得擦涂、覆盖原始记录。住院研究参与者的原始化验单均可在医院的HIS系统上溯源,其化验结果均需填写至病例报告表的相应的表格里。 原始记录(原始病历、检查报告单等)需妥善保存。病例报告表的数据均来源于原始病历,由研究者填写,每个入选获得编码的病例必须完成病例报告表。完成的病例报告表由主要研究者审查后交数据管理员,进行数据录入与管理工作。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

The investigator fills in the CRF in time after following up the study participants to ensure that the content on the case report form is consistent with the content on the outpatient or inpatient medical record. The case report form can only be crossed out if any correction is made, and the corrected data should be signed by the researcher (the pinyin abbreviation of the researcher's name signed) and dated, and the original record shall not be erased or overwritten. The original test forms of inpatient study participants can be traced on the hospital's HIS system, and the test results must be filled in the corresponding form of the case report form. Original records (original medical records, examination reports, etc.) should be properly preserved. The data in the case report form are derived from the original medical record, filled in by the researcher, and each selected case must complete the case report form. The completed case report form will be reviewed by the principal investigator and submitted to the data manager for data entry and management.
