Reconsidering indoor radon monitoring strategies in Romanian medical buildings: a data-driven perspective.
Article in Frontiers in public health, 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
Introduction: Medical buildings are complex indoor environments with heterogeneous room functions, occupancy patterns and HVAC (especially ventilation) requirements. Although radon monitoring methodologies are applied across workplaces, healthcare facilities differ from residential buildings in air exchange, operational schedules and functional zoning. This study investigated indoor radon concentration in Romanian medical buildings and assessed whether current monitoring assumptions, including residential-derived seasonal correction factors, adequately reflect observed exposure patterns. Materials and methods: A total of 1700 CR-39 detectors were installed for three-month measurements in 115 medical institutions from 40 localities across Romania. After retrieval, 1,651 valid measurements were included in the final analysis. Annual indoor radon activity concentration (AIRAC) was estimated using seasonal correction factors recommended by the Romanian methodology. Mixed-effects models were fitted separately for log-transformed uncorrected three-month radon concentrations and seasonally corrected AIRAC, with floor level, facility type and starting month as fixed effects and building code as a random intercept. Results: Overall radon levels were low, with an arithmetic mean of 61 Bq/m Discussion: Radon variability in medical buildings appears shaped by floor level, facility type and building-specific characteristics. The comparison between corrected and uncorrected seasonal patterns showed that the application of residential seasonal correction factors was associated with an amplified warm-cold contrast and a stronger starting-month pattern in AIRAC estimates. Conclusion: This first large-scale assessment of indoor radon in Romanian medical buildings supports a risk-based and context-sensitive monitoring strategy. Detector allocation should prioritize lower levels and facility categories associated with higher concentrations, while the use of residential seasonal correction factors in medical buildings should be further evaluated through repeated seasonal measurements.
