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

There is a pressing need for longitudinal studies which examine the stability of the sinonasal microbiota. In this study, we investigated bacterial and fungal community composition of the sinuses of four healthy individuals every month for one year, then once every three months for an additional year to capture seasonal variation. Sequencing of bacterial 16S rRNA genes and fungal ITS2 revealed communities that were mainly dominated by members of Actinobacteria and Basidiomycota, respectively. We observed overall shifts in both bacterial and fungal community diversity that were attributable to a combination of individual, seasonal and annual changes. The results suggest that each of the subjects possessed a strong bacterial sinonasal signature, but that fungal communities were less subject specific. Differences in fungal and bacterial diversity between subjects, and which OTUs may be correlated with seasonal differences, were investigated. A small core community that persisted throughout the two year sampling period was identified: Corynebacterium, Propionibacterium and Staphylococcus, and one type of fungus, Malassezia restricta. It is likely that bacterial and fungal airway microbiomes are dynamic and experience natural shifts in diversity with time. The underlying reasons for these shifts appear to be a combination of changes in environmental climate and host factors.
