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

The aim of this work was to investigate the occurrence of invertase (Inv) in cyanobacteria. We describe the first isolation and characterization of prokaryotic alkaline/neutral Inv (A/N-Inv) genes. Two genes (invA and invB) were identified in Anabaena sp. PCC 7120, which share about 50-56% identity with plant A/N-Inv and encode proteins of about 53-55 kDa. The identification of these proteins was confirmed by biochemical and immunological studies with recombinant proteins and with the enzymes isolated from Anabaena cells. Expression analysis supported the important role of A/N-Inv in nitrogen-fixing growth conditions. Nevertheless, A/N-Inv activities were shown in all filamentous and unicellular cyanobacteria investigated, regardless of their capacity to fix dinitrogen. Searches in complete sequenced genomes showed that A/N-Inv homologues are restricted to cyanobacterial species and plants. In particular, filamentous nitrogen-fixing strains display two A/N-Inv genes and unicellular strains have only one. Phylogenetic analysis leads us to suggest that modern plant A/N-Inv might have originated from an orthologous ancestral gene after the endosymbiotic origin of chloroplasts.
