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

Diverse bacteria use proteinaceous microcompartments (MCPs) to optimize metabolic pathways that have toxic or volatile intermediates. MCPs consist of metabolic enzymes encased within a protein shell that provides a defined environment. In Salmonella enterica, a MCP is involved in B(12)-dependent 1,2-propanediol utilization (Pdu MCP). In this report, we show that the protein PduM is required for the assembly and function of the Pdu MCP. The results of tandem mass spectrometry and Western blot analyses show that PduM is a component of the Pdu MCP. Electron microscopy shows that a pduM deletion mutant forms MCPs with abnormal morphology. Growth tests and metabolite measurements establish that a pduM deletion mutant is unable to form functional MCPs. PduM is unrelated in sequence to proteins of known function and hence may represent a new class of MCP structural proteins. We also report a modified protocol for the purification of Pdu MCP from Salmonella which allows isolation of milligram amounts of MCPs in about 4 h. We believe that this protocol can be extended or modified for the purification of MCPs from diverse bacteria.
