1 · What the graph read from it

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.

2 · The registry

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

Fluorescence in situ hybridization analysis of a reciprocal translocation in maize between chromosomes 1 and 5 that has been used extensively in maize genetics revealed the presence of an inactive centromere at or near the breakpoints of the two chromosomes. This centromere contains both the satellite repeat, CentC, and the centromeric retrotransposon family, CRM, that are typical of centromere regions in maize. This site does not exhibit any of the tested biochemical features of active centromeres such as association with CENP-C and phosphorylation of serine-10 on histone H3. The most likely scenario for this chromosome arrangement is that a centromere was included in the repair process that formed the translocation but became inactive and has been inherited in this state for several decades. The documentation of an inactive A chromosome centromere in maize extends the evidence for an epigenetic component to centromere function in plants. This case provides an experimental example of how karyotype evolution might proceed via changes in centromere inactivation.
