Assessment of Mental Health in Healthcare Workers Involved in Care of Victims of the 2017 Las Vegas Mass Shooting.

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
introductionMass shooting incidents (MSI) are single events injuring four or more victims, and they occur in the United States on average every 12.5 days. Studies have examined the psychological impact of MSIs on witnesses and surviving victims. However, the mental health of healthcare workers involved in the care of MSI victims requires further examination. We explored the association between work-related stress and symptoms of depression, anxiety, and post-traumatic stress disorder (PTSD) in healthcare workers involved in the 2017 Las Vegas mass shooting.
methodsSurveys were distributed to 170 healthcare workers involved in the care of victims of the largest MSI in US history, the 2017 Las Vegas Route 91 Harvest Festival (58 people killed, 413 wounded bv gunshot or shrapnel). Fifty healthcare workers (29.4% response rate; 68% female), 29-71 years of age, responded to demographic questions followed by the Beck Anxiety Inventory, Beck Depression Inventory-II (BDI-II), Patient Health Questionnaire-9 (PHQ-9), PTSD Checklist for the Diagnostic and Statistical Manual of Mental Disorders, 5
resultsResults showed that work-related stress was significantly associated with symptoms of depression (BDI-II: P < .001, 22.9% variance; PHQ-9: P < .05, 20.5% variance) and PTSD (P < .001, 26.8% variance). No significant differences in symptom severity (work-related stress, anxiety, depression, and PTSD) were found between participants involved in critical care and non-critical care (P > .05). In addition, healthcare workers reported higher symptoms of depression (5.18 vs 2.91, P < .001), and lower symptoms of anxiety (8.84 vs 22.35, P < .05) than normative data of the general population.
conclusionHealthcare workers reporting a higher risk of work-related stress were more likely to report more symptoms of depression and PTSD. Healthcare workers involved in critical and non-critical care reported similar symptoms of anxiety, depression, PTSD, and work-related stress. Moreover, healthcare workers involved in the care of the Las Vegas mass shooting victims were more likely to report more symptoms of depression and fewer symptoms of anxiety than samples of the general population. Given the novelty of this study, the unpredictability of MSIs, and the current limitations, we offer recommendations for future studies.
