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
backgroundAcute poisoning is a growing challenge to emergency departments (EDs). Our aim is to investigate the recent epidemiological and clinical characteristics of patients with acute poisoning and the impact of the COVID-19 pandemic on the disease pattern.
methodsThis retrospective study included patients with acute poisoning through the medical records from EDs at three tertiary hospitals in Jiangsu Province, China, from January 2017 to April 2023. Their epidemiological and clinical profiles were investigated and analyzed under each category of poisoning. In parallel, the enrolled patients were also divided into the pre-COVID (January 2017-December 2019) and amid-COVID (January 2020-April 2023) groups to derive the differences between them.
resultsFor 1,876 patients enrolled, their mean age was 49.5 ± 21.1 years, where the female-to-male ratio (FMR) was 1.1. The most common toxic substances were pesticides (31.6%), drugs (31.1%), and alcohol (17.1%). Predominantly, acute poisoning occurred at domiciliary sites (76.4%) and with intention (52.9%). Inpatients were much older than outpatients (52.0 ± 21.9 years versus 47.6 ± 20.2 years). Amid the COVID-19 pandemic, the patients with acute poisoning became much younger, and the cases of alcohol poisoning became more frequent. With the increasing cases of acute poisoning, the patient admissions to hospital and intensive care unit (ICU) were both decreased.
conclusionEpidemiological results revealed that the acute poisoning by pesticides and drugs occurred primarily at home and through suicidal attempts. The most susceptible age to a given poisoning may differ, but a working-age group remains the largest population of intentionally or unintentionally poisoned victims. The impact of COVID-19 pandemic on acute poisoning was prominent, which significantly altered the epidemiological and clinical characteristics.
