1 · What the graph read from it

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.

2 · The registry

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

backgroundSymbiotic nitrogen-fixation between bacteria called rhizobia and leguminous plants is a critical aspect of sustainable agriculture. Complex, two-way communication governs the invasion of plant roots and the formation of nodules in which the rhizobia reduce N

resultsWe examined the symbiotic relevance of the genes on the 1.68 Mb pSymB chromid of the model rhizobium Sinorhizobium meliloti. By employing a strain in which pSymB was removed, we used a gain-of-function approach to assess a select group of known symbiotic regions totalling 261 kb (15.5%) of pSymB. This gene set enabled symbiotic N

conclusionsThe reduction of the pSymB genome showcases the complexity and nuance of its involvement in the N
