1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Electronic health record (EHR) data must be mapped to standard information models for interoperability and to support research across organizations. New information models are being developed and validated for data important to nursing, but a significant problem remains for how to correctly map the information models to an organization's specific flowsheet data implementation. This paper describes an approach for automating the mapping process by using stacked machine learning models. A first model uses a topic model keyword filter to identify the most likely flowsheet rows that map to a concept. A second model is a support vector machine (SVM) that is trained to be a more accurate classifier for each concept. The stacked combination results in a classifier that is good at mapping flowsheets to information models with an overall f2 score of 0.74. This approach is generalizable to mapping other data types that have short text descriptions.
