The invention relates to the technical field of clinical test
information extraction, and discloses an
information extraction method of a clinical test scheme. According to the method, clinical test scheme files, registration information, research papers and related literatures are collected, data are sorted, an
electronic database is formed, a
text mining technology and a
natural language processing tool are used, the collected literatures are analyzed, key information is labeled, and the literatures are analyzed. Calculating a random
control test design type proportion and an open
label design type proportion, extracting the marked data into a spreadsheet, checking the extracted data, implementing
double check, calculating a consistency proportion and an error rate in the checking process, and performing
statistical analysis according to the extracted data, so as to obtain a
statistical analysis result; calculating a mean value, a standard deviation and a
confidence interval, extracting a minimum value and a maximum value of data and a combination effect quantity of a combination end point, arranging analysis results into a report, including detailed description of
test design, key results and conclusions, and displaying by using charts and graphs.
