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

objectivesThis study aimed to clarify the current clinico-epidemiological characteristics of acute pancreatitis (AP) in Japan.

methodsWe conducted a two-stage nationwide survey of patients with AP treated at selected hospitals in 2021, during the COVID-19 pandemic. The first stage estimated the total number of AP patients, while the second collected detailed clinical data.

resultsThe estimated number of AP patients requiring hospitalization was 61,080, with an overall incidence rate of 49 per 100,000 persons, decreasing from 78,450 in 2016. Detailed clinical data were obtained for 4,375 patients, including 1,362 (31.1%) classified as severe. The male-to-female ratio was 2.0, with mean ages at onset of 60.1 years for males and 65.4 years for females. The three major causes were alcohol (31.2%), gallstones (22.5%), and idiopathic etiology (22.1%). The AP-associated in-hospital mortality rate was 2.1% in all AP and 5.3% in severe cases, down from 6.1% in the 2016 survey. Antibiotics were administered to 61.2% of mild cases, a significant reduction from 94.5% in 2016. Enteral nutrition was provided to 56.9% of severe cases, up from 31.8% in 2016. Among 124 patients undergoing interventional drainage for walled-off necrosis, 57 were treated using a step-up approach. Notably, no patients underwent upfront surgery as the initial treatment.

conclusionsDuring the pandemic, the estimated number of AP cases requiring hospitalization declined for the first time in nearly four decades. Mortality in severe cases improved, and adherence to clinical guidelines on prophylactic antibiotics and enteral nutrition also improved, indicating enhanced management of AP in Japan.
