Type 2 Inflammatory Biomarker Response After Exercise Challenge Testing.
Article in Journal of asthma and allergy, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
introductionExercise-induced bronchoconstriction is due to osmotic stimulus of the airway epithelium and leads to a cascade of biomarker release from several inflammatory cells. Several type 2 (T2) mediators have been linked to exercise-induced bronchoconstriction, but the T2 response per se has not been described during exercise. The aim of this study was therefore to investigate T2 biomarkers in plasma and urine from subjects with asthma and healthy controls before and after an exercise challenge.
methodsTwenty-two subjects with mild asthma and 18 healthy controls performed an exercise challenge test on a treadmill, and fractional exhaled NO (FeNO) was measured at baseline. Blood and urine samples were collected repeatedly during 60 min after the test and Interleukin-13 (IL-13), thymus and activation-related chemokine (TARC), periostin and leukotrienes were measured.
resultsAsthmatics and controls showed similar levels of IL-13, TARC, periostin and Cys-LT in plasma at baseline, and there were no differences in baseline levels between subjects with a negative and positive exercise challenge. After exercise, there was an overall increase in interleukin-13 (IL-13) in plasma in all subjects (p<0.001), with a peak at 10 min after the exercise challenge in both the asthmatic and control group. An increase in TARC in plasma was also seen (p<0.001), but only in the control subjects. In contrast, Cys-LT in plasma showed an overall decrease in all subjects (p<0.001), while periostin in plasma did not change. In conjunction with plasma, the level of IL-13 was increased in urine 30 min after the exercise challenge (p=0.002) and decreased again at 60 min (p=0.004). Similarly, leukotriene E DISCUSSION: In conclusion, circulating levels of IL-13 are increased after exercise to the same extent in asthmatics and healthy control subjects, which indicates a physiological rather than a pathophysiological response. Also, the levels of TARC and leukotrienes were affected after exercise.
