OBJECTIVE: For many literature review tasks, including systematic review (SR) and
other aspects of evidence-based medicine, it is important to know whether an
article describes a randomized controlled trial (RCT). Current manual annotation
is not complete or flexible enough for the SR process. In this work, highly
accurate machine learning predictive models were built that include confidence
predictions of whether an article is an RCT. MATERIALS AND METHODS: The LibSVM
classifier was used with forward selection of potential feature sets on a large
human-related subset of MEDLINE to create a classification model requiring only
the citation, abstract, and MeSH terms for each article. RESULTS: The model
achieved an area under the receiver operating characteristic curve of 0.973 and
mean squared error of 0.013 on the held out year 2011 data. Accurate confidence
estimates were confirmed on a manually reviewed set of test articles. A second
model not requiring MeSH terms was also created, and performs almost as well.
DISCUSSION: Both models accurately rank and predict article RCT confidence. Using
the model and the manually reviewed samples, it is estimated that about 8000 (3%)
additional RCTs can be identified in MEDLINE, and that 5% of articles tagged as
RCTs in Medline may not be identified. CONCLUSION: Retagging human-related
studies with a continuously valued RCT confidence is potentially more useful for
article ranking and review than a simple yes/no prediction. The automated RCT
tagging tool should offer significant savings of time and effort during the
process of writing SRs, and is a key component of a multistep text mining
pipeline that we are building to streamline SR workflow. In addition, the model
may be useful for identifying errors in MEDLINE publication types. The RCT
confidence predictions described here have been made available to users as a web
