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

backgroundSeveral researchers have reported that the amount of protein intake is associated with lung function and airflow obstruction. However, few studies have investigated the effect of low protein intake on acute exacerbations of chronic obstructive pulmonary disease. This study aimed to investigate the effect of low protein intake on exacerbations in mild to moderate chronic obstructive pulmonary disease.

methodsWe used data obtained from the Korean National Health and Nutrition Examination Survey (KNHANES) between 2007 and 2012, linked to the National Health Insurance claims data. The clinical outcomes and the rate of exacerbation were retrospectively compared between the low protein intake group and the non-low protein intake group which was stratified by quartile categories of protein intake in 2,069 patients with mild to moderate chronic obstructive pulmonary disease.

resultsThe low protein intake group was significantly associated with older age, women, never smoker, low household income, and low education level, compared with the non-low protein intake group. The low protein intake group was significantly associated with increased hospitalization (18.0%

conclusionsLow protein intake was associated with an increased risk of exacerbations in mild to moderate chronic obstructive pulmonary disease. The data are available at the KNHANES website (https://knhanes.cdc.go.kr).
