Article in BMC emergency medicine, 2025. 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
backgroundEmergency medical dispatch is a crucial component of a national healthcare system. This study provides the first comprehensive analysis of the temporal patterns of emergency medical service evaluations in Ulaanbaatar, Mongolia, and evaluates the impact of COVID-19 lockdowns on those patterns.
methodsWe analyzed emergency medical evaluations recorded by physicians following the dispatch calls received by the Emergency Medical Communication Center in Ulaanbaatar between 2016 and 2021. We assessed trends in the number of emergency calls, demographic distributions, and temporal patterns. Comparative analysis was conducted to assess the impact of COVID-19 lockdowns, with a focus on seasonal, weekly, and hourly variations.
resultsThere were 558,457 emergency calls during the study period, and a total of 8 diagnoses (I, J, Y, F, K, G, O, and Z according to ICD-10) constituted 99.1% of the emergency calls. The two most abundant causes for emergency calls in Ulaanbaatar are “Diseases of the circulatory system (I)” and “Diseases of the respiratory system (J)” in all seasons. We analyzed the temporal patterns of the calls and identified that the highest number of calls was received in winter, weekends, and evenings for the total number of calls. Further, we conducted an analysis of calls during COVID-19 strict lockdown periods. A retrospective analysis of the impacts of the COVID-19 pandemic on emergency calls showed that emergency calls decreased by 24% compared to the previous year. Notably, the difference between the COVID-19 strict lockdown period and the preceding period was more pronounced during periods of strict lockdown implementation.
conclusionsThis is the first comprehensive analysis of EMS calls in Ulaanbaatar from 2016 to 2021, providing valuable insights into both long-term temporal trends and the effects of pandemic-related lockdowns. These findings can support improved EMS planning and inform public health policies in low- and middle-income countries. CLINICAL TRIAL NUMBER: Not applicable.
