A nopA deletion mutant of Sinorhizobium fredii USDA257, a soybean symbiont, is impaired in nodulation.
Article in Current microbiology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
Sinorhizobium fredii USDA257 employs type III secretion system (T3SS) to deliver effector proteins into the host cells through pili. The nopA protein is the major component of USDA257 pili. The promoter region of USDA257 nopA possesses a well conserved tts box. Serial deletion analysis revealed that the tts box is absolutely essential for flavonoid induction of nopA. Deletion of nopA drastically lowered the number of nodules formed by USDA257 on cowpea and soybean cultivar Peking. In contrast to the parental strain, the USDA257 nopA mutant was able to form few nodules on soybean cultivars McCall and Williams 82. Light and transmission electron microscopy examination of these nodules revealed numerous starch grains both in the infected and uninfected cells.
