1 · What the graph read from it

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.

2 · The registry

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

purposeIncreasing the number of physicians per population may improve the quality of medical services, but there are few reports on this aspect in the field of surgery. This study aimed to examine whether the number of physicians is associated with the number of nighttime emergency surgeries, which may be one of the indicators of the quality of medical services in the field of surgery.

methodsThis was a prefecture-based ecological study utilizing open data from Japanese government surveys conducted between 2015 and 2019. The relationship between the number of physicians and the number of nighttime emergency surgeries in 47 prefectures of Japan was evaluated by correlation analysis and panel data regression analysis. The correlation analysis was conducted between the number of physicians per 100,000 population and the number of nighttime emergency surgeries per 100,000 population per year in each prefecture in Japan. In the panel data regression analysis, panel data of the prefectures in Japan from 2015 to 2019 were created. We evaluated whether the number of physicians was related to the number of nighttime emergency surgeries, independent of the number of acute care beds per 100,000 population, population density, and the elderly population ratio.

resultsFrom the correlation analysis, the correlation coefficient between the number of physicians per 100,000 population and the number of nighttime emergency surgeries per 100,000 population was 0.533 (P < 0.001). In the panel data regression analysis, there was a significant association between the number of physicians per 100,000 population and the number of nighttime emergency surgeries per 100,000 population (P < 0.001). The regression coefficient (95% confidence interval) for the number of physicians per 100,000 population was 0.246 (0.113-0.378).

conclusionThe number of physicians is associated with the number of nighttime emergency surgeries.
