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

Rapid identification of copy-number variations (CNVs) is crucial in prenatal diagnosis; however, current chromosomal microarray analysis (CMA) has a lengthy turnaround time. We evaluated the feasibility of low-pass nanopore sequencing for genome-wide CNV detection using amniotic fluid and umbilical cord blood from 22 samples. Combining the enzymatic reaction step with nanopore sequencing or the nCNV-seq technique achieved complete concordance with CMA across all abnormal and normal cases, accurately detecting CNVs as small as 0.7 Mb. The workflow generated > 1 million reads per sample, providing sufficient coverage (< 1×) for reliable CNV profiling. These findings demonstrate that nanopore sequencing can serve as an alternative to CMA for rapid testing, potentially lower investment costs, and faster turnaround times.
