Fantastic stewards and where to find them: a descriptive study of the heterogeneous disparity in physician-pharmacist-nurse distribution among the infectious disease workforce.

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
Background: Infectious disease (ID) care involves a diverse range of professionals, yet the shortage and geographical disparity of ID physicians, among other professionals, remain underexplored. This cross-sectional descriptive study aimed to elucidate the distribution of ID physicians, infection control (IC) pharmacists, and IC nurses in Japan, focusing on the interrelations among the ID workforce within medically relevant geographical units. Methods: Publicly available data from 335 secondary medical areas (SMAs) in Japan, with a population of 125 million, were analyzed. Workforce distribution was assessed using the Gini index to quantify inequalities and spatial clustering across the SMAs per capita, per hospital bed, and per unit area. χ2 test was used to assess the association of hospital characteristics with the presence of each professional. Findings: The research subjects were 1,729 ID physicians, 1,371 IC pharmacists, and 2,657 IC nurses, whose workplace data were available in Japan as of 2023. The Gini coefficients for the densities of ID physicians, IC pharmacists, and IC nurses per 100,000 people were 0.46, 0.34, and 0.28, respectively. The density of the ID workforce per unit area (1,000 km Conclusions: The substantial variation in ID workforce composition across SMAs suggests opportunities for both regional and national policy and identifies new avenues for improving access to ID care.
