Rates of adverse and serious adverse events in children with cystic fibrosis.
Article in Journal of cystic fibrosis : official journal of the European Cystic Fibrosis Society, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundCystic fibrosis (CF) is an autosomal recessive disease characterized by chronic sinopulmonary symptoms and chronic gastrointestinal symptoms that begins in infancy. Children with CF are increasingly being included in clinical trials. In order to fully evaluate the impact of new therapies in future clinical trials, an understanding of baseline adverse event (AE) rates in children with CF is needed. To address this, we determined the rates of common AEs in pediatric patients with CF who participated in two clinical trials.
methodsWe reviewed AEs for placebo recipients in the AZ0004 study and inhaled tobramycin recipients in the Early Pseudomonas Infection Control (EPIC) clinical trial. AEs were categorized based on Medical Dictionary for Regulatory Activities (MedDRA) coding classifications and pooled into common, batched AE descriptors. AE rates were estimated from negative binomial models according to age groups, severity of lung disease, and season.
resultsA total of 433 children had 8,266 total AEs reported, or 18.1 (95% CI 17.0, 19.2) AEs per person per year. Respiratory AEs were the most commonly reported AEs, with a rate of 7.6 events per person-year. The total SAE rate was 0.33 per person per-year. Cough was the most commonly reported respiratory AE, with 61% of subjects reporting at least one episode of cough within 4 months. The rate ratio of any AE was higher in Spring, Fall, and Winter, compared with Summer.
conclusionsAEs occur commonly in pediatric CF clinical trial participants. Season of enrollment could affect AE rates.
