Patient Preferences and Understanding of Genome-Wide Cell-Free DNA Screening for Foetal Chromosomal Imbalances: A Survey Study.

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
objectiveTo assess parental preferences, expectations and understanding of genome-wide cell-free DNA screening (gwNIPT) in Australia.
methodA cross-sectional survey study utilizing an anonymous electronic questionnaire was conducted across three participating screening services in Australia between September 2023 and November 2024. Questions pertained to respondent demographics, pre-screening counselling, and accuracy expectations of gwNIPT for various chromosomal anomalies. Statistical analyses to investigate associations between responses used Chi-squared and Fisher's exact tests, ordinal logistic regression, and the Kruskal-Wallis test.
resultsThere were 329 survey responses recorded, of which 216 were completed (65.7%). The most frequent source of NIPT referral was a medical doctor (74.1%), and the most common duration of pre-screening counselling was 5 minutes (41.0%). Respondents showed overwhelming interest in all anomalies included in gwNIPT as well as various phenotypic outcomes including those of uncertain clinical significance. Despite this, only a minority of patients were aware that they were undergoing genome-wide screening (38.2%), and respondents did not anticipate a statistically significant difference in screening accuracy across different anomaly types (p = 0.715).
conclusionRespondents undergoing gwNIPT indicated a preference to receive as much genetic information about their pregnancies as possible. Pre-screening counselling should therefore include the limitations of gwNIPT.
