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
Evolution of heterochromatic regions in the B long arm was studied in two directions: construction of a phylogenetic tree from mutational variants of CL-repeat and analysis of the XbaI fragments carrying CL-repeat and the repeat structural variants. Using tertiary trisomes and hypoploids of a set of B-10L translocations, the fragments associated with CL-repeat and the variants in each of the three distal heterochromatic (DH) regions were identified. Twenty fragments comprising the CL-repeat were observed in the B-chromosome, and each was assigned to an individual DH region. Four deletions, one insertion, and a large number of mutational variants from each of the three DH regions were isolated and sequenced. The sequences of 27 mutational variants were used to establish a phylogenetic tree which divided the 27 variants into three groups, each of which was associated with a distinct DH region and elucidated an evolution order of the three DH regions. According to the tree, the DH2 was the earliest DH region, which gave rise to the DH3 to be followed by the DH1. The distributions of the fragments including CL-repeat and structural variants in the three DH regions were consistent with such evolution order.
