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
key messageBy removing the Rf (multi) locus from chromosome 1BS of wheat via chromosome engineering we were able to generate a resource for the production of male sterile wheats in three new cytoplasms. Cytoplasmic male sterility is an essential component in the development of many hybrid crops. In wheat (Triticum aestivum L.) only the cytoplasm of T. timopheevi cytoplasm has been extensively tested even though many other cytoplasms are also known to produce male sterility. Among them are the cytoplasms of Ae. kotschyi, Ae. uniaristata and Ae. mutica but here male sterility manifests itself only when the 1RS.1BL rye-wheat translocation is present in the nuclear genome. The location of the male fertility restoring gene on the chromosome arm 1BS (Rf (multi) ) has recently been determined using a set of primary recombinants of chromosome arms 1RS with 1BS. Using this knowledge the same recombinants were used to create chromosome arm 1BS in wheat with a small insert from rye that removes the restorer locus. The disomic engineered chromosome 1B1:6 assures male sterility in all three cytoplasms and any standard chromosome 1B in wheat is capable of restoring it. This newly engineered chromosome in combination with the three cytoplasms of Aegilops sp extends the range of possibilities in attempts to create a viable system for hybrid wheat production.
