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

Bovine leukemia virus (BLV) and human T-cell leukemia virus types 1 and 2 (HTLV-1 and HTLV-2) belong to the same subfamily of oncoviruses. Defective HTLV-1 proviral genomes have been found in more than half of all patients with adult T-cell leukemia examined. We have characterized the genomic structure of integrated BLV proviruses in peripheral blood lymphocytes and tumor tissue taken from animals with lymphomas at various stages. Genomic Southern hybridization with SacI, which generates two major fragments of BLV proviral DNA, yielded only bands that corresponded to a full-size provirus in all of 23 cattle at the lymphoma stage and in 7 BLV-infected but healthy cattle. Long PCR with primers located in long terminal repeats clearly demonstrated that almost the complete provirus was retained in all of 27 cattle with lymphomas and in 19 infected but healthy cattle. However, in addition to a PCR product that corresponded to a full-size provirus, a fragment shorter than that of the complete virus was produced in only one of the 27 animals with lymphomas. Moreover, when we performed conventional PCR with a variety of primers that spanned the entire BLV genome to detect even small defects, PCR products were produced that specifically covered the entire BLV genome in all of the 40 BLV-infected cattle tested. Therefore, it appears that at least one copy of the full-length BLV proviral genome was maintained in each animal throughout the course of the disease and, in addition, that either large or small deletions of proviral genomes may be very rare events in BLV-infected cattle.
