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

Prokaryotic microbes possess a variety of appendages on their cell surfaces. The most commonly known surface appendages of bacteria include flagella, pili, curli, and spinae. Although archaea have archaella (archaeal flagella) and various types of pili that resemble those in bacteria, cannulae, and hami are unique to archaea. Typically involved in cell motility, flagella, the thickest appendages, are 20-26 nm and 10-14 nm wide in bacteria and archaea, respectively. Bacterial and archaeal pili are distinguished by their thin, short, hair-like structures. Curli appear as coiled and aggregative thin fibers, whereas spinae are tubular structures 50-70 nm in diameter in bacteria. Cannulae are characterized by ∼25 nm-wide tubules that enter periplasmic spaces and connect neighboring archaeal cells. Hami are 1-3 μm in length and similar to barbed grappling hooks for attachment to bacteria. Recent advances in specimen preparation methods and image processing techniques have made cryo-transmission electron microscopy an essential tool for in situ structural analysis of microbes and their extracellular structures.
