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.
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
Investment in cybersecurity is critical to protect information system security, preserve organizational interests, and fulfil social responsibilities. However, due to the lack of a transparent process, investors often struggle to assess the effectiveness of their investments. Traditional return on security investment (ROSI) can be considered as an economic indicator which reflects investment efficiency, but it often emphasizes investment costs and anticipated returns while overlooks cybersecurity related metrics. This paper proposes the FAIR-ROSI model that integrates five qualitative and quantitative cybersecurity metrics with the Factor Analysis of Information Risk (FAIR) model. It combines practical qualitative and quantitative indicators to enhance the granularity of the traditional ROSI model. We then use a case study to evaluate the FAIR-ROSI model. The results from pre and post control measures shows a narrow margin between actual and projected loss values and a significantly higher ROI compared to the total security expenditure.
