Surgical treatment of diabetic foot: a spatial analysis, Ceará, Brazil, 2016-2021.

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
objectiveTo identify the spatial pattern of surgical treatment of diabetic foot complications in Ceará.
methodsThis was an observational spatial analysis study conducted in Ceará. We calculated the annual incidence rate of diabetic foot surgery. This rate was standardized with the indirect method using the mean year (2018). Subsequently, the rate was smoothed using the local empirical Bayes method. Furthermore, the Getis-Ord Gi* technique was applied to identify clustered areas of high incidence. Finally, a purely spatial scan was performed to identify relative risk (RR) for each municipality in Ceará, with those with a RR>1 presenting a higher risk for the event of interest.
resultsBetween 2016 and 2021, 7,319 hospitalizations for surgical treatment of complicated diabetic foot were recorded in Ceará, especially in the Fortaleza macro-region (49.8%; n=3,650). In the spatial analysis, both the crude rates, as well as the rates after local empirical Bayes smoothing, show greater concentration in the following macro-regions: Fortaleza, Sertão Central, Sobral and Cariri. This information was confirmed by local Moran's I and the Getis-Ord Gi* statistic (p-value <0.05). The scan revealed that 30.5% (n=56) of the state's municipalities presented RR>1.
conclusionThe study revealed a spatial pattern marked by concentration of diabetic foot surgical treatment cases in the Fortaleza macro-region and, after Bayes smoothing, revealed a shift in the distribution of cases to two of the state's interior-region municipalities, Quixadá and Aracoiaba.
