Recurrent power outages and the mental health burden of grid reliability in Maryland.
Article in iScience, 2026. 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
Power outages are increasingly shaped by aging infrastructure, climate stress, and rising electricity demand. Their mental health consequences remain poorly quantified, particularly for routine outages outside major disasters. Here, we link 15-min outage records with Maryland Healthcare Cost and Utilization Project State Inpatient Database records from 2018 to 2023 and estimate ZIP-quarter associations with hospitalizations for primary mental health diagnoses. Higher outage exposure was consistently associated with increased hospitalization rates in Poisson pseudo-maximum likelihood models with ZIP code and year-quarter fixed effects and controls for weather, socioeconomic conditions, demographics, healthcare access, and comorbidity. The baseline incidence rate ratio was approximately 1.017, equivalent to a 1.7% increase per one-unit increase in logged outage episodes. Results were robust to alternative thresholds and concentrated among frequent 1-3h disruptions. Instrumental-variable analyses based on grid infrastructure yielded larger positive estimates. These findings suggest that grid reliability is a climate-adaptation and health-system continuity issue.
