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

Several lines of evidence demonstrated body mass index (BMI) to be inversely associated with outcomes of patients with HF, so-called obesity paradox. However, the relationship between BMI and outcomes of patients with HF in Japan has been poorly understood. This study sought to explore the relationship between BMI and in-hospital mortality of patients hospitalized for heart failure (HF) in Japan and whether BMI at hospital admission could be used for the risk stratification of hospitalized HF patients. We studied 407,722 patients hospitalized for HF between January 2010 and March 2018, using the Diagnosis Procedure Combination database, a national inpatient database in Japan. Patients were categorized into four groups: underweight (BMI < 18.5 kg/m
