盲法:

双盲,安慰剂与VitD3(800IU)均由国药控股星鲨制药(厦门)有限公司提供,安慰剂与VitD3在形状、大小、颜色等外观上都与VitD3相同,但在外盒上标注“A”或“B”,且研究过程采用双盲法(研究者与孕妇均不知道“A”和“B”分别代表安慰剂或VitD3)。

Blinding:

Double-blind, Placebo and VitD3 (800 IU) are provided by Xingsha pharmaceutical (xiamen) co., LTD., the placebo are same as the VitD3 in shape, size, color and appearance, but labeled "A" or "B" on the outer, and double blinded method (researchers and pregnant women don't know "A" and "B" represent the placebo or VitD3) will be applied.

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:

数据采集:采用问卷调查的方法收集研究对象入组基线信息、孕期随访信息、分娩信息以及产后母亲及子代随访信息;利用医院电子病历系统收集研究对象产检信息和分娩信息。 数据管理:问卷由专人负责录入epidata,数据由专人负责整理保存。

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

Data collection: Use questionnaire survey to collect baseline information, pregnancy follow-up information, delivery information, and postpartum maternal and offspring follow-up information. The hospital electronic medical record system will be used to collect the antenatal care data and delivery information of the study subjects. Data management: The questionnaire will be input into epidata by a special person, and the data will be sorted and saved by a special person.
