Patient time on the EMR was calculated from first date of a progress note and a physician bill on the same date to the date of the most recent data extraction.
Extracting the relevant information from the structured abstracted, complemented as required by consulting the full text, was considered the most efficient and appropriate data extraction strategy given the aims of this review.
We focused on medical reviews instead of other reviews because the FDA medical reviews are, as we learned during pilot-testing of data extraction, most likely the review documents where the FDA reviewers address the issue of outcome selection.
The analysis for patient time on EMR was done by assessing both the EMR fields and the CPP fields in the one year prior to the most recent date of data extraction for patients that had a record in the EMR for <1 year, 1-2 years, 2-3 yeand and >3 years.
For the 104 articles included in the data extraction, most of the first authors were based in North America (40) and the UK (30), with others based in Scandinavian countries (9), Australia and New Zealand (9), South Africa (6), and a range of other countries in Africa, Asia and Europe (10).
A well structured literature search was carried out and most of the relevant studies identified; however, the manufacturer excluded most of these from the data extraction process.
A manager who had been responsible for handling most of the government's data extraction requests left the team to work in a different part of the company, according to four current and former Apple employees, who spoke on the condition of anonymity because they were not authorized to speak publicly about the changes.
AImed, BioInfer, IEPA, HPRD50 and LLL are the five annotated PPI corpora that are most commonly used for PPI data extraction, and were used in this study to construct training datasets [ 19].
The data extraction method most commonly used was the questionnaire (46 studies, 78%), followed by the questionnaire and physical examination combined (5 studies, 8.5%), the interview (4 studies, 6.8%), the questionnaire and interview combined (2 studies, 3.4%), and the interview and physical examination combined (2 studies, 3.4%).
The predefined form used for data extraction documented the most relevant items including author's name, year of publication, study location, number of patients, methylation detection method, methylation rate and follow-up.
