Fluorescence in situ hybridization with cosmid clones for the detection of human cytomegalovirus DNA in peripheral blood leukocytes.

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.
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
Radioactive in situ hybridization techniques or enzymatic detection procedures of hapten-modified human cytomegalovirus (HCMV) probes have been widely used for studying the infection of peripheral blood leukocytes with HCMV. This report describes significant improvements in terms of signal resolution which can be obtained by applying a highly sensitive fluorescence in situ hybridization (FISH) technique in conjunction with a large subgenomic HCMV DNA probe. Three cosmid clones spanning 119.1 kb of the HCMV genome (230 kb) were used to construct the digoxigenin-11-dUTP-labeled probe which was found to be superior to a total HCMV probe representing the entire genome. Crucial hybridization parameters were analyzed systematically in order to ensure optimal resolution power and sensitivity. The protocol was successfully applied to HCMV-infected fibroblasts and peripheral blood leukocytes of 12 transplant patients and unambiguously facilitated the precise intracellular localization of HCMV genomes in infected cells. Because of its excellent resolution properties, accompanied by the virtual absence by any background staining, we recommend the use of this protocol as a sensitive approach for further virological analyses of the interactions between HCMV and peripheral blood leukocytes at the single-cell level.
