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

Introduction: This study aimed to analyze the epidemiological characteristics of imported malaria in China, identify transmission risks from the global malaria burden and China's international population exchanges, and propose a two-stage prevention and control strategy for overseas and post-entry periods of outbound personnel. Methods: A descriptive epidemiological analysis was performed on the National Infectious Disease Surveillance Information System, including the number of patients with imported malaria, Results: Between 2017 and 2024, 16,571 patients with imported malaria, including 75 deaths, were reported, with a U-shaped temporal trend. The annual number of patients with imported malaria remained stable at 2,600-2,800 from 2017 to 2019, dropped to 798 in 2021, and rebounded to 3,155 in 2024. Conclusion: The global malaria epidemic and China's international exchanges have increased the pressure on malaria importation. Strengthening multisectoral collaboration in health services for outbound personnel and improving targeted surveillance and treatment capacity in key post-entry areas are crucial to prevent severe illness, deaths, and secondary transmission and to consolidate China's malaria elimination achievements.
