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
The structure and organization of the 5S ribosomal DNA units of the silver fir, Abies alba Mill., as well as their position in the chromosome complement were investigated. PCR amplification of the gene and nontranscribed spacer region, sequence analysis and Southern hybridization, using a homologous probe, detected DNA sequences of approximately 550 bp and 700 bp. Sequence analysis of the spacers revealed that the difference in length between the sequences occurred in the middle spacer region as a result of the amplification of a 75-bp sequence of the short unit class, which is organized in four 54- to 68-bp tandem repeats in the long spacer unit. The 5S rDNA transcribed region is 120 bp long and shows high sequence similarity with other gymnosperm species. The comparative analysis of 5' and 3' flanking sequences of 5S rRNA genes of silver fir and other gymnosperms indicates that A. alba spacer units have the same rate of evolution and are more closely related to Larix and Pseudotsuga than to Pinus and Picea. Southern hybridization and fluorescence in situ hybridization of metaphase chromosomes of A. alba suggest that the short and long spacer units are organized as separate tandem arrays at two chromosomal loci on chromosomes V and XI.
