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
backgroundAsthma is an airway inflammatory disease driven by multiple factors with a high incidence in children and adolescents. Environmental tobacco smoke exposure (TSE) and diet are inducing factors for asthma. The potential of omega-3 polyunsaturated fatty acids (PUFAs) to alleviate asthma symptoms by their anti-inflammatory effects has been explored. However, to date, no studies have explored the effect of dietary PUFAs intake on the asthma in children and adolescents exposed to tobacco smoke.
objectiveWe aimed to examine the effect of dietary PUFAs intake on the current asthma in children and adolescents exposed to tobacco smoke.
methodsData of this cross-sectional were extracted from the National Health and Nutrition Examination Survey (NHANES) 2007-2018. Children and adolescents with serum cotinine concentration ≥ 0.05 ng/mL were defined to exposed to tobacco smoke. Dietary PUFAs intake information were obtained from 24 h recall interview. The weighted univariate and multivariate were utilized to explore the effect of PUFAs on the association of asthma and TSE, with adjusted odds ratios (AORs) and 95% confidence intervals (CIs). These moderating effects were further explored based on the age, gender and body mass index (BMI) and sedentary time.
resultsTotally, 7981 eligible children and adolescents were included, with the mean age of 11.96 ± 0.06 years old. Of whom, 1.024 (12.83%) had current asthma. After adjusted all covariates, we found children and adolescents with TSE had high occurrence of current asthma (AOR = 1.2, 95% CI 1.03-1.63); We also found omega-3 PUFAs intake (P for interaction = 0.010), not omega-6 PUFAs (P for interaction = 0.546), has a moderating effect on the association of TSE and current asthma. Moreover, we further observed that children and adolescents with TSE and low omega-3 PUFAs intake had high occurrence of current asthma (AOR = 1.58, 95% CI 1.19-2.10), while no significant association was found in children and adolescents with high omega-3 PUFAs intake (all P > 0.05). This moderating effect was more prominent in children and adolescents aged ≤ 12 years old (AOR = 1.62, 95% CI 1.06-2.47), girls (AOR = 2.14, 95% CI 1.15-3.98), overweight (AOR = 1.87, 95% CI 1.01-3.47) and sedentary time > 6 h (AOR = 1.96, 95% CI 1.00-3.86).
conclusionWe found dietary omega-3 PUFAs plays a moderating effect on the association of asthma and TSE in children and adolescents, especially in children and adolescents aged ≤ 12 years, girls, overweight or sedentary time > 6 h. This moderating effect suggested higher omega-3 intake has potential benefits in decreasing the occurrence of asthma in children and adolescents who exposed to tobacco smoke.
