Association Between Mediterranean Diet and the Incidence of Adult-Onset Asthma in the SUN Project: A Spanish Prospective Cohort Study.

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
introductionDietary factors have been suggested as drivers of asthma in children and adults. However, evidence is inconclusive. The aim of this study was to explore the Mediterranean diet (MedDiet) and its association with asthma incidence in the SUN project, an adult cohort of Mediterranean heritage. MATERIAL AND
methodsDietary habits and asthma diagnosis were collected from the SUN cohort study (Seguimiento Universidad de Navarra). Adult-onset asthma was defined as self-reported diagnosis in the last 2 years, recorded in any of the follow-up questionnaires completed every 2 years in adults free of airway disease at baseline. Food frequency questionnaire was assessed at baseline and at 10 years follow up. We measured the Mediterranean Diet Score (MDS) as an indicator of adherence to the MedDiet. We generated four categories of adherence to the MedDiet based on the MDS (0 to 9 range score). We used multivariable repeated-measurement Cox models adjusted for potential confounders.
resultsFrom 17,127 participants followed up for a mean of 12.8 years, 302 (1.76%) reported a new diagnosis of asthma. In the multivariable analysis a significant negative association was seen between the risk of newly diagnosed asthma and the MDS. Those participants with the highest adherence to the MedDiet (MDS ≥ 7 points) showed a lower risk of asthma than those with the lowest adherence (MDS ≤ 2 points) (Hazard Ratio: 0.58; 95% Confidence Interval: 0.36-0.95; p-trend = 0.02).
conclusionTo our knowledge, this is the first study conducted in an adult Mediterranean population that has found a significant association between greater adherence to the Mediterranean diet and a lower incidence of asthma in adults.
