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 Arabidopsis AtMYB80 transcription factor (formerly AtMYB103) regulate genes essential for tapetal and pollen development. One of these genes, coding for an aspartic protease (UNDEAD), may control the timing of tapetal programmed cell death (PCD). In crop plants such as rice and wheat, abiotic stresses lead to abnormal tapetal development resulting in delayed PCD. Manipulation of AtMYB80 function has been used to develop a reversible male sterility system applicable to hybrid crop production. MYB80 homologs were cloned from wheat, rice, canola and cotton. The promoters of the homologs drove temporal and spatial expression patterns of the GUS reporter gene in the tapetum and microspores of Arabidopsis anthers identical to the AtMYB80 promoter. A short region is conserved in all five MYB80 promoters. The MYB80 homolog genes, driven by the AtMYB80 or their respective promoters, rescued the atmyb80 mutant, completely restoring male fertility. The canola MYB80 was fused to the EAR (ERF-associated amphiphilic repression) repressor and canola plants transgenic for the construct exhibited premature tapetal degradation and subsequent pollen abortion. The five MYB80 homologs all shared a 44 amino acid sequence immediately adjacent to the R2R3 domain which appears to be necessary for MYB80 function.
