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

We describe the application of a new DNA-scanning method, which has been termed Cleavase Fragment Length Polymorphism (CFLP; Third Wave Technologies, Inc., Madison, Wis.), for the determination of the genotype of hepatitis C virus (HCV). CFLP analysis results in the generation of structural fingerprints that allow discrimination of different DNA sequences. We analyzed 251-bp cDNA products generated by reverse transcription-PCR of the well-conserved 5'-noncoding region of HCV. We determined the genotypes of 87 samples by DNA sequencing and found isolates representing 98% of the types typically encountered in the United States, i.e., types 1a, 1b, 2a/c, 2b, 3a, and 4. Blinded CFLP analysis of these samples was 100% concordant with DNA sequencing results, such that closely related genotypes yielded patterns with strong familial resemblance whereas more divergent sequences yielded patterns with pronounced dissimilarities. In each case, the aggregate pattern was indicative of genotypic grouping, while finer changes suggested subgenotypic differences. We also assessed the reproducibility of CFLP analysis in HCV genotyping by analyzing three distinct isolates belonging to a single subtype. These three isolates yielded indistinguishable CFLP patterns, as did replicate analysis of a single isolate. This study demonstrates the suitability of this technology for HCV genotyping and suggests that it may provide a low-cost, high-throughput alternative to DNA sequencing or other, more costly or cumbersome genotyping approaches.
