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

In this paper, we demonstrate the use of synthetic polyamide probes to fluorescently label heterochromatic regions on human chromosomes for discrimination in cytogenetic preparations and by flow cytometry. Polyamides bind to the minor groove of DNA in a sequence-specific manner. Unlike conventional sequence-specific DNA or RNA probes, polyamides can recognize their target sequence without the need to subject chromosomes to harsh denaturing conditions. For this study, we designed and synthesized a polyamide to target the TTCCA-motif repeated in the heterochromatic regions of chromosome 9, Y and 1. We demonstrate that the fluorescently labeled polyamide binds to its target sequence in both conventional cytogenetic preparations of metaphase chromosomes and suspended chromosomes without denaturation. Chromosomes 9 and Y can be discriminated and purified by flow sorting on the basis of polyamide binding and Hoechst 33258 staining. We generate chromosome 9- and Y-specific 'paints' from the sorted fractions. We demonstrate the utility of this technology by characterizing the sequence of an olfactory receptor gene that is duplicated on multiple chromosomes. By separating chromosome 9 from chromosomes 10-12 on the basis of polyamide fluorescence, we determine and differentiate the haplotypes of the highly similar copies of this gene on chromosomes 9 and 11.
