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 temporal dynamics of soil bacterial communities are understudied, but such understanding is critical to elucidating the drivers of community variation. The goal of this study was to characterize how soil bacterial communities vary across diurnal, sub-seasonal and seasonal time-scales in a 5.8 m2 plot and test the hypothesis that bacterial diversity varies on each of these scales. We used 16S rDNA gene amplicon sequencing to quantify the alpha and beta diversity of soil bacteria as well as the Net Relatedness Index and Nearest Taxon Indices to assess the degree of phylogenetic clustering, and the extent to which community shifts were driven by stochastic vs. deterministic limitation. We found that species richness was highest in winter, lowest in fall and that communities were compositionally distinct across seasons. There was no evidence of diurnal-scale shifts; the finest temporal scale over which community shifts were detected using our DNA-based analysis was between sampling dates separated by 6 weeks. Phylogenetic analyses suggested that seasonal-scale differences in community composition were the result of environmental filtering and homogeneous selection. Our findings provide insight into temporal variation of soil bacterial communities across the hourly to seasonal scales while minimizing the potential confounding effect of spatial variation.
