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

Aim: We aimed at comparing data extractions from randomized controlled trials by using Elicit and human reviewers. Background: Elicit is an artificial intelligence tool which may automate specific steps in conducting systematic reviews. However, the tool's performance and accuracy have not been independently assessed. Methods: For comparison, we sampled 20 randomized controlled trials of which data were extracted manually from a human reviewer. We assessed the variables study objectives, sample characteristics and size, study design, interventions, outcome measured, and intervention effects and classified the results into "more," "equal to," "partially equal," and "deviating" extractions. STROBE checklist was used to report the study. Results: We analysed 20 randomized controlled trials from 11 countries. The studies covered diverse healthcare topics. Across all seven variables, Elicit extracted "more" data in 29.3% of cases, "equal" in 20.7%, "partially equal" in 45.7%, and "deviating" in 4.3%. Elicit provided "more" information for the variable study design (100%) and sample characteristics (45%). In contrast, for more nuanced variables, such as "intervention effects," Elicit's extractions were less detailed, with 95% rated as "partially equal." Conclusions: Elicit was capable of extracting data partly correct for our predefined variables. Variables like "intervention effect" or "intervention" may require a human reviewer to complete the data extraction. Our results suggest that verification by human reviewers is necessary to ensure that all relevant information is captured completely and correctly by Elicit. Implications: Systematic reviews are labor-intensive. Data extraction process may be facilitated by artificial intelligence tools. Use of Elicit may require a human reviewer to double-check the extracted data.
