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

Candidatus Profftella armatura (Betaproteobacteria) is an organelle-like defensive symbiont inhabiting the symbiotic organ of a devastating citrus pest, the Asian citrus psyllid Diaphorina citri. Previous two-dimensional electron microscopy hinted at unprecedented ultrastructures in Profftella, but their precise architecture and composition were unknown. Here, using serial block-face scanning electron microscopy, high-voltage electron tomography, and fluorescence in situ hybridization, we show that elongated Profftella cells (2.8-136 μm observed) contain multiple tubes (1-43 per cell) up to 45 μm long. These tubes, occupying ~6.3% of the cell volume, are composed of five or six fibers twisted into a right-handed helix with a consistent diameter of ~230 nm. Their stability under high vacuum suggests a mechanical support role in elongated Profftella. Close association with ribosomes implies a possible role in protein synthesis. Our findings provide insight into the structural adaptations of intracellular symbionts and may inform strategies for controlling citrus pests.
