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

BACs-on-Beads (BoBs™) assay is a rapid aneuploidy test (RAT) that detects numerical chromosomal aneuploidies and multiple microdeletion/microduplication syndromes. This study was conducted to appraise the usefulness of the BoB™ assay as a complementary diagnostic tool to conventional karyotyping for the rapid detection of chromosomal aneuploidies. A total of 485 prenatal (amniotic fluid and chorionic villi) and blood/products of conception samples were collected between July 2013 and August 2018, and analyzed by the BoBs™ assay and cytogenetic karyotyping and further validated by fluorescence in situ hybridization (FISH). Forty-three of 484 qualifying samples (8.9%) were identified as abnormal by the BoBs™ assay. The assay was comparable to karyotyping in the detection of common structural abnormalities (trisomy 21, trisomy 18, X, and Y), with a sensitivity of 96.0% and a specificity of 100%. BoBs™ assay detected 20 microdeletion and microduplication syndromes that were missed by karyotyping. BoBs™, however, missed 10 cases of polyploidies and chromosomal rearrangements which were identified by conventional karyotyping. Our findings suggest that BoBs™ is a reliable RAT which is suitable in combination with conventional karyotyping for the detection of common aneuploidies. The assay also improves the diagnostic yield by recognizing clinically relevant submicroscopic copy number gains and losses.
