Fall patterns and outcomes after a moderate urban earthquake without structural collapse: a retrospective cohort from Istanbul.
Article in Injury epidemiology, 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
backgroundModerate earthquakes - where structural collapse is absent - represent an underexplored public health challenge. In such events, injuries arise not from building failure but from behavior-associated injury mechanisms. This study aims to characterize injury patterns and mechanisms among individuals presenting to a tertiary emergency department following the 6.2 Mw Istanbul earthquake of April 23, 2025, and to identify implications for community-level behavioral preparedness.
methodsThis retrospective study was conducted at a tertiary care hospital serving a catchment population of approximately 750,000 in Istanbul, Turkiye. All individuals presenting to the emergency department within 12 h of the earthquake were included. Cases were identified using the ICD-10 code X34 (earthquake victim). Demographic data, injury mechanisms, anatomical injury sites, need for medical and surgical intervention, and clinical outcomes were recorded. Statistical analysis was performed using IBM SPSS Statistics version 31.0.
resultsA total of 66 individuals were included, representing more than 1/3 of all earthquake-related injuries reported across Istanbul. The mean age was 30.5 ± 13.0 years; 54.5% were male. All recorded injuries were classified as behavior-associated injury mechanisms: same-level falls (W18, 40.9%), falls from stairs (W10, 37.9%), falls or jumps from height (Y30, 12.1%), impact with objects (W22, 6.1%), and entrapment between objects (W23, 3.0%). Injuries coded as W10 and Y30 were significantly more likely to require advanced medical intervention (p < 0.001) and surgical treatment (p = 0.002). The lower extremity was the most commonly affected region (65.2%). Eleven patients (16.7%) required surgical intervention; no deaths occurred.
conclusionsIn this cohort, all recorded injuries were classified as behavior-associated injury mechanisms. These findings suggest that earthquakes without major structural collapse may represent an important and potentially preventable public health burden.
