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
aimTo evaluate the association between reported symptoms upon exposure to airborne allergens and sensitization to the corresponding allergen.
methodIn a population-based cohort, 1647 children aged 12 years were interviewed about symptoms from eyes, nose and lower airways upon exposure to birch, timothy, cat, dog, and horse, and were afterwards skin prick tested for the same allergens. Positive predictive value (PPV) was calculated for reported symptoms in relation to sensitization.
resultsThe prevalence of sensitization was generally higher in boys than girls, while reporting of symptoms was equal upon exposure. The proportion of sensitization among individuals reporting symptoms ranged from 70% to 95% and was highest for lower airway symptoms upon dog and cat exposure. Lower airway symptoms were the least prevalent but had the highest PPV for sensitization to each allergen (PPV = 75%-95%). The increasing number of symptoms when exposed to a specific allergen increased the likelihood of sensitization, and the PPV for three symptoms upon cat and dog exposure was > 95%.
conclusionsSelf-reported symptoms upon aeroallergen exposure highly predict sensitization to the same allergen. Unless allergen-immunotherapy is indicated, objective measurements of sensitization may not always be necessary in 12-year-old children with a convincing history of airborne allergy.
