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
Inheritance of resistance to cyst nematode (Heterodera sacchari) in Oryza sativa was investigated by inoculation tests with isolate 244 from Congo in segregating populations derived from hybridisation between O. sativa and its African sister cultivated species, O. glaberrima. We found that the resistance was controlled by one major gene, Hsa-1(Og), with codominance of susceptible and resistant alleles. To map Hsa-1(Og) on the rice genome, we pooled the data obtained from segregation of the resistance trait and microsatellite markers in three kinds of progeny: BC(1)F(3), BC(1)F(4), and pseudo-F(2) populations. Hsa-1(Og) was unambiguously located between Cornell University's RM206 and RM254 markers on chromosome 11. Two additional microsatellite markers derived from Monsanto publicly available sequences were found to be tightly linked to the Hsa-1(Og) gene. It is possible that numerous plant resistances to a pathogen in fact exhibit a codominant inheritance, possibly explaining misleading conclusions in several reports on resistance segregation.
