1 · What the graph read from it

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.

2 · The registry

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

backgroundRecruiting a sufficient number of patients is often a challenge for conducting clinical trials. Published data reveal that only 10% of eligible patients according to inclusion and exclusion criteria are enrolled in clinical trials. Consequentially, identifying barriers and facilitators may improve enrollment. These factors may differ in the pediatric population, for example, due to the involvement of parents in the decision-making process. We aimed to conduct an overview of systematic reviews to summarize the barriers and facilitators influencing the enrollment of pediatric participants in clinical trials.

methodsA systematic literature search in PubMed and Epistemonikos of published systematic reviews focusing on barriers and facilitators influencing the enrollment of pediatric patients in clinical trials was conducted. Study selection, data extraction, and quality assessment were performed by two authors independently. The methodological quality was judged using a critical appraisal tool. Finally, data were narratively synthesized.

resultsOf 283 identified systematic reviews, four met the inclusion criteria and were included in the overview. Parents belonging to an ethnic minority or having low socioeconomic status were identified as barriers to enrollment whereas higher parental education and higher age served as facilitators. Additionally, existing expectations, previous treatment experiences and preferences, study duration, type of control group, and the child's attitude toward study participation could favor or hinder participation. Furthermore, physicians' opinions of study-related treatments may also influence the enrollment process.

conclusionThis overview provides a summary of barriers and facilitators to the enrollment of pediatric patients in clinical trials. Taking into account this information may enhance the enrollment of this hard-to-reach population.
