Analysis of the Activities of a Physician-Staffed Helicopter in the Coronavirus Disease 2019 Pandemic Phase.

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
objectiveThe purpose of this study was to investigate changes in the duration of activity of a physician-staffed helicopter emergency medical service (HEMS) in Eastern Shizuoka Prefecture before and during the coronavirus disease 2019 pandemic.
methodsWe retrospectively investigated the duration of dispatch activities from February 2020 to June 2021 (pandemic group, n = 1,032) and from April 2016 to January 2020 (control group, n = 3,054).
resultsThere were no significant differences in the average age, percentage of male patients, interval from the request of HEMS dispatch to arrival, interval from arrival at the scene to leaving the scene, interval from leaving the scene to arrival at the hospital, or the ratio of requests for HEMS dispatch from the local fire department between the control and pandemic groups. In contrast, the interval from the first call to HEMS dispatch in the control group was significantly shorter than that in the pandemic group, and the ratio of requests for HEMS dispatch before contacting patients in the control group was significantly greater than that in the pandemic group.
conclusionThe interval from the first call to HEMS dispatch was prolonged in the COVID-19 pandemic period. However, the actual activity time of the HEMS was not affected.
