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

Fimbriae of Porphyromonas gingivalis are filamentous appendages on the cell surface and are thought to be one of the virulence factors. The fimA gene encoding the subunit protein of fimbriae, fimbrillin (FimA), was classified into four typeable variants (types I to IV). We previously examined the distribution of P. gingivalis in terms of fimA genotypes in periodontitis patients using a fimA type-specific PCR assay. However, some patients harbored P. gingivalis with untypeable fimA. In this study, we have cloned a new type (type V) of fimA from dental plaque samples. P. gingivalis with type V fimA was isolated from dental plaque of a periodontitis patient, and the isolate was named HNA-99. The deduced amino acid sequences were compared with those of type I P. gingivalis ATCC 33277, type II strain HW24D1, type III strain 6/26, and type IV strain HG564, and the homologies were found to be 45, 44, 43, and 55%, respectively. Southern blot analysis showed that the clinical isolate HNA-99 possessed P. gingivalis-specific genes sod and kgp. However, in terms of serological specificities, type V FimA showed a difference from other types of FimA. In addition, type V P. gingivalis bacteria were detected in 16.4% (12 of 73) of the P. gingivalis-positive patients with periodontitis by PCR assay using specific primers. Thus, a new type of fimA gene is now established, and the fimA genotyping could be useful in determining the disease-associated genotypes of P. gingivalis involved in the development of adult periodontitis.
