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.

Abstract

aimsInflammation is central in atrial fibrillation (AF) pathophysiology, but the temporal association between inflammatory activity and AF remains uncertain. This study investigated the day-to-day relationship between plasma C-reactive protein (CRP) levels and AF occurrence in continuously monitored individuals. METHODS AND

resultsPost hoc analysis of the LOOP study randomizing participants with stroke risk factors to implantable loop recorder (ILR) screening (n = 1501) or usual care. ILR raw data were linked to blood samples collected within 1 day. The outcome was AF episodes lasting ≥60 min. Associations were examined using generalized and linear mixed models and as a self-controlled case series (SCCS). ILR and CRP data were available for 1065 participants combining >1.2 million days of heart rhythm monitoring (including ∼40 000 days with AF) with >7000 CRP measurements. CRP was higher during days with AF (geometric mean 8.37 [7.11-9.86] mg/L) vs. non-AF days (4.02 [3.71-4.35] mg/L). Each doubling of CRP was associated with 36% higher odds of AF (adjusted odds ratio [aOR] 1.36 [1.26-1.47]). Compared with CRP ≤3 mg/L, the odds of AF increased for CRP >10-50 and >50 mg/L (aOR 3.50 [2.18-5.60] and 5.75 [3.48-9.50], respectively). In SCCS analyses, CRP >10 mg/L was associated with higher incidence of AF compared to lower levels (incidence rate ratio 2.41 [1.53-3.80]).

conclusionThis exploratory study found a temporal and dose-response relationship between CRP levels and AF occurrence, supporting inflammation as an acute trigger and underscoring the need to evaluate inflammatory markers as potential targets in AF management.
