Source Data:- Source documents are original documents, data, and records from which participants' CRF data are obtained. These include, but are not limited to, hospital records (from which medical history and previous and concurrent medication may be summarised into the CRF), clinical and office charts, laboratory and pharmacy records, diaries, microfiches, radiographs, and correspondence. CRF entries will be considered source data if the CRF is the site of the original recording (e.g., there is no other written or electronic record of data). Specifically, for this study the CRF will be used as the source document for all anthropometrics, questionnaire and biochemistry that is collected during the study visits and copy of the biochemistry and anthropometric results will be put into the patient medical notes.
