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

rationaleUsing principal components analysis to examine dietary patterns complements the evaluation of individual food and nutrient intake in relation to health outcomes, but has not yet been applied to nonmalignant respiratory disease or symptoms.

objectiveTo examine the relation between patterns of dietary intake at baseline and new onset of persistent cough with phlegm in a population-based cohort of Singapore Chinese.

methodsA 165-item validated food frequency questionnaire was administered in-person at baseline in 1993. We identified 623 cases of incident cough with phlegm among 52,325 subjects by telephone interview from 1999 through 2004. We identified two distinct food patterns: a "meat-dim sum" pattern characterized by pork and chicken dim sum foods and noodle dishes, and a "vegetable-fruit-soy" pattern characterized by vegetables, fruit, and soyfood items. MAIN

resultsThe meat-dim sum pattern was positively associated with new-onset cough with phlegm (odds ratio, 1.43; 95% confidence interval, 1.08, 1.89; comparing fourth to first quartile, p for trend = 0.02), after adjustment for age, sex, total energy intake, smoking, education, and nonstarch polysaccharide intake, a protective factor for cough with phlegm in this cohort. Weaker associations were seen for more chronic symptoms and for incident asthma. A weak inverse association for the vegetable-fruit-soy pattern disappeared after adjustment for nonstarch polysaccharide intake.

conclusionA diet rich in meats, sodium, and refined carbohydrates may increase risk of developing cough with phlegm, independently of the apparent beneficial effects of a diet high in fiber in this Singapore Chinese cohort.
