The impact of data breach on IT investment at neighboring hospitals: Evidence from California Hospitals.
Article in Digital health. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: This study investigates the effect of data breach incidents on IT investment at neighboring hospitals. Methods: Hospital data are collected from the California Department of Health Care Access and Information and matched with the breach archive provided by the U.S. Department of Health and Human Services Office for Civil Rights to construct a set of breached hospitals. Using a community detection algorithm, neighborhoods of hospitals are constructed to serve as the treatment group of breached hospitals against unaffected hospitals. To control for potential differences between affected and unaffected communities, hospitals are matched using propensity score matching. Subsequently, the effect of data breach incidents on IT investment at neighboring hospitals is estimated using a difference-in-differences model. Results: Analysis of hospital financial data from 2011 to 2017 revealed that neighboring hospitals responded to hacking/IT data breaches with a statistically significant 51% increase ( Conclusion: Data breaches involving hacking/IT incidents at a neighboring hospital could nudge a hospital toward increased IT capital investment. This may result from neighboring hospitals acknowledging the need to take preventive measures. Hospitals should be strategically encouraged to reinforce cybersecurity capacity to minimize loss from future attacks.
