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

We used both cultivation and direct recovery of bacterial 16S rRNA gene (rDNA) sequences to investigate the structure of the bacterial community in anoxic rice paddy soil. Isolation and phenotypic characterization of 19 saccharolytic and cellulolytic strains are described in the accompanying paper (K.-J. Chin, D. Hahn, U. Hengstmann, W. Liesack, and P. H. Janssen, Appl. Environ. Microbiol. 65:5042-5049, 1999). Here we describe the phylogenetic positions of these strains in relation to 57 environmental 16S rDNA clone sequences. Close matches between the two data sets were obtained for isolates from the culturable populations determined by the most-probable-number counting method to be large (3 x 10(7) to 2.5 x 10(8) cells per g [dry weight] of soil). This included matches with 16S rDNA similarity values greater than 98% within distinct lineages of the division Verrucomicrobia (strain PB90-1) and the Cytophaga-Flavobacterium-Bacteroides group (strains XB45 and PB90-2), as well as matches with similarity values greater than 95% within distinct lines of descent of clostridial cluster XIVa (strain XB90) and the family Bacillaceae (strain SB45). In addition, close matches with similarity values greater than 95% were obtained for cloned 16S rDNA sequences and bacteria (strains DR1/8 and RPec1) isolated from the same type of rice paddy soil during previous investigations. The correspondence between culture methods and direct recovery of environmental 16S rDNA suggests that the isolates obtained are representative geno- and phenotypes of predominant bacterial groups which account for 5 to 52% of the total cells in the anoxic rice paddy soil. Furthermore, our findings clearly indicate that a dual approach results in a more objective view of the structural and functional composition of a soil bacterial community than either cultivation or direct recovery of 16S rDNA sequences alone.
