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 study analyzes the spatial characteristics of the epidemic. It evaluates the effectiveness of its differentiated prevention and control policies implemented at different stages of the epidemic in the Yangtze River Delta.
methodsThe study divided the epidemic into 2 stages and analyzed the spatial evolution characteristics of the COVID-19 epidemic in the region by using Anselin Local Moran's I and standard deviation ellipse.
resultsIn the first stage, the high value of confirmed cases was concentrated in the eastern and southern cities. The trajectory of the barycenter showed a V-shaped change characterized by a southward shift followed by a northward fluctuation. In contrast, the second stage was mainly concentrated in Jiangsu Province and Shanghai, and the Barycenter did not change over time. The diversified prevention and control measures enabled 'zero new cases' in the Yangtze River Delta within a month.
conclusionThe prevention and control policy implemented in the Yangtze River Delta has worked well. With the global pandemic of COVID-19, it is recommended that other countries follow the example of the Yangtze River Delta, tighten prevention policies, and speed up vaccination to avoid a rebound of the epidemic.
