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

backgroundPeriodontal disease could be a risk factor for rheumatoid arthritis (RA). It is assumed that the bacterial strain Porphyromonas gingivalis mediates citrullination of host peptides and thereby the generation of RA-associated autoantibodies in genetically predisposed individuals. For that reason non-RA individuals who suffered from generalized aggressive (GAgP, N = 51) and generalized chronic periodontitis (GChP, N = 50) were investigated regarding the occurrence of antibodies against citrullinated cyclic peptides (anti-CCP) and citrullinated α-enolase peptide-1 (anti-CEP-1) in comparison to non-RA non-periodontitis controls (N = 89). Furthermore, putative associations between infections with five periodontopathic bacteria or expression of certain human leucocyte antigens (HLA) to these autoantibodies were investigated.

methodsThe presence of anti-CCP and anti-CEP-1 in plasma samples was conducted with enzyme linked immunosorbent assay. Subgingival plaque specimens were taken from the deepest pocket of each quadrant and pooled. For detection of DNA of five periodontopathic bacteria PCR with sequence specific oligonucleotides was carried out. Low resolution HLA typing was carried out with PCR with sequence specific primers. Differences between patients and controls were assessed using Chi square test with Yates correction or Fisher`s exact test if the expected number n in one group was <5.

resultsTwo patients with GAgP (3.9%), no patient with GChP and two controls (2.2%, pFisher = 0.662) were positive for anti-CEP-1 whereas no study participant was anti-CCP positive. Individuals with P. gingivalis were slightly more often anti-CEP-1 positive in comparison to individuals without P. gingivalis (3.2 vs. 1.1%, pFisher = 0.366). Carrier of HLA-DQB1*06 or the HLA combination DRB1*13; DRB3*; DQB1*06 were slightly more anti-CEP-1 positive (6.1 and 4.3%) than no carriers (0.7 and 0%, pFisher 0.053).

conclusionsGAgP and GChP and the presence of periodontopathic bacteria are not associated with an increased risk for occurrence of anti-CCP and anti-CEP-1 autoantibodies. The putative relationship between periodontitis and RA should be investigated in further studies.
