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
LTR retrotransposons belong to a major group of DNA sequences that are often localized in plant centromeres. Using BAC inserts originating from the centromere of a monosomic wild beet (Beta procumbens) chromosome fragment in Beta vulgaris, two complete LTR retrotransposons were identified. Both elements, designated Beetle1 and Beetle2, possess a coding region with genes in the order characteristic for Ty3-gypsy retrotransposons. Beetle1 and Beetle2 have a chromodomain in the C-terminus of the integrase gene and are highly similar to the centromeric retrotransposons (CRs) of rice, maize, and barley. Both retroelements were localized in the centromeric region of B. procumbens chromosomes by fluorescence in-situ hybridization. They can therefore be classified as centromere-specific chromoviruses. PCR analysis using RNA as template indicated that Beetle1 and Beetle2 are transcriptionally active. On the basis of the sequence diversity between the LTR sequences, it was estimated that Beetle1 and Beetle2 transposed within the last 60,000 years and 130,000 years, respectively. The centromeric localization of Beetle1 and Beetle2 and their transcriptional activity combined with high sequence conservation within each family play an important structural role in the centromeres of B. procumbens chromosomes.
