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 messageThis paper describes the development of monosomic alien addition and disomic introgression lines through a cross between autotetraploid indica rice and Oryza punctata toward tapping valuable traits for rice improvement. Oryza punctata is a distantly related wild Oryza species having BB genome with untapped genetic resources for rice improvement. Low crossability between the cultivated O. sativa and O. punctata restricts the success of transferring many desirable traits into cultivated rice. Artificially induced autotetraploids of an elite breeding line, IR31917-45-3-2, were produced and crossed with O. punctata. Allotriploid F1 plants were backcrossed to IR31917-45-3-2 and generated progenies with extra chromosomes from O. punctata. Twenty BC1F1 and 59 BC2F1 plants were produced with chromosome numbers ranging from 24 (2n) to 29 (2n + 5) and 2n (24) to 26 (2n + 2), respectively. Eleven monosomic alien addition lines (MAALs) were characterized morphologically and cytologically and designated as MAAL 1-12. MAALs were genotyped using O. punctata genome-specific molecular markers and detected chromosome segments inherited from O. punctata. O. punctata introgressions across all the chromosomes of O. sativa were identified except for chromosome 8. The most frequent introgressions were observed in chromosomes 4, 6, 10, and 11, which could be the recombination hotspots between A and B genomes. Some of the qualitative traits such as black hull, purple coleoptile base, purple stigma, long awn, and short grain size from O. punctata were inherited in some disomic introgression lines (DILs). Several DILs inherited genes from O. punctata conferring resistance to brown planthopper, green leafhopper, and diseases such as bacterial blight and blast. This is the first report on successful gene transfer from O. punctata into O. sativa.
