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

introductionPresence of chronic low grade inflammation has often been implicated in the etiology of atrial fibrillation (AF). Whether pre-existing inflammatory state promotes AF or initiation of AF activates inflammation is a dilemma among clinicians. This study investigates the role of high sensitive C reactive protein (hs-CRP) and interleukin 6 (IL-6) in AF with rheumatic mitral stenosis (Rh-MS) as markers of chronic inflammation.

methodsThis case control cohort included sixty five (n=65) Rh-MS patients having other valve lesions as trivial to mild. Out of them twenty nine (n=29; group C) had baseline AF and rest were normal sinus rhythm (NSR). A 24h holter recording was done in NSR patients to diagnose paroxysmal AF/tachyarrhythmia forming group B (n=12) and not having any tachyarrhythmia were designated as NSR; group A (n=24).

resultshs-CRP and IL6 showed statistically significant increase in group C (permanent AF) compared to group A (95% CI: 4.2-0.9, p=0.007; 95% CI: 1.2-0.89; p=0.05 respectively), while it was non significant between group A and group B (p>0.05). A weak positive correlation was observed with hs-CRP and left atrial volume index (LAVi) (r=0.45, p=0.06) in AF group as compared to NSR group. 68.2% of patients in AF group (27/41) had moderate to severe spontaneous echo contrast (SEC) as compared to 37.5% (10/24) in NSR group.

conclusionIncreased hs-CRP and IL-6 levels in the paroxysmal and permanent AF group may favour the hypothesis that low grade chronic inflammation could be the cause of atrial fibrillation than a consequence.
