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 B-chromosome of maize contains an A-chromosome centromere-specific satellite CentC repeat in its centromere region (CENB) and at multiple locations in its distal heterochromatic regions (BDHs). Because CentC is highly repetitive, it is a challenge to study CentC sequences within individual centromeres or chromosome regions. The combined structure of CentC and a BDH-specific CL-repeat has allowed us to isolate CentC sequences from BDHs. In the study described herein, we have used a PCR method to amplify 13 CL-CentC variant products that were specifically mapped to A-centromeres (CENAs), the CENB, and BDHs via the tertiary trisomes and hypoploids of five B-10L translocations. Cloning and sequence analyses of these CL-CentC products have revealed a local CentC homogenization within the three CentC-containing regions. Phylogenetic analysis has indicated that the CentC sequences of BDHs are more closely related to those of CENAs in comparison to that of the CENB. Furthermore, the CentC monomers that are within the CENB are more diverse than those within BDHs and CENAs. These results shed light on the evolution of CentC repeats on the B-chromosome and provide a better understanding of B-chromosome evolution.
