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

objectivePeriodontitis is associated with cardiovascular diseases (CVD). In our previous studies a prothrombotic state has been observed in periodontitis, which contributes to the risk of CVD. The aim of this study was to investigate whether serum IgG levels against Aggregatibacter actinomycetemcomitans (Aa) and Porphyromonas gingivalis (Pg) in periodontitis were associated with a prothrombotic state. MATERIALS AND

methodsPatients with moderate (n = 38) and severe periodontitis (n = 30) and controls (n = 24) were recruited. We explored correlations between serum anti-Aa and anti-Pg IgG and plasma levels of markers of prothrombotic state (von Willebrand Factor [vWF], prothrombin fragment 1+2 [F1+2], plasminogen activator inhibitor-1 [PAI-1] and D-dimer). Multivariate analyses were performed considering several major potential contributing factors.

resultsPeriodontitis patients showed higher anti-Aa IgG (p = 0.015) than controls but not for Pg (p = 0.320). In periodontitis patients, body mass index and anti-Aa IgG showed a positive correlation with vWF (β = 0.297, p = 0.010 and β = 0.248, p = 0.033 respectively).

conclusionsIn periodontitis, infection with Aa together with other well accepted risk factors for CVD, may play a role in increasing the risk for prothrombotic state.
