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

purposeTo assess efficacy of radiofrequency catheter ablation (RFCA) for atrial fibrillation (AF) in rheumatic heart disease (RHD) patients with mild mitral stenosis (MS).

methodsThis retrospective cohort study included 62 consecutive RHD patients with mild MS and AF and 124 AF patients without RHD with matched age, gender, AF types as control. Procedure endpoints were defined as circumferential pulmonary vein ablation (CPVA) for paroxysmal AF, CPVA plus bidirectional block of lines, and disappearance of complex fractionated atrial electrograms for non-paroxysmal patients in both groups.

resultsCumulative success rate during the total follow-up (RHD, 23-140 months; control, 24-140 months) was lower in RHD group than control (32.3 vs. 56.5%, log-rank P = 0.006). In RHD patients, the success rate was higher in paroxysmal AF patients than non-paroxysmal AF patients during the mid-term follow-up (55.0 vs. 26.2%, log-rank P = 0.041), and was similar between the two AF types during the total follow-up (45.0 vs. 26.2%, log-rank P = 0.130). Patients without mitral regurgitation (MR) or with mild MR had a higher success rate than patients with moderate MR during the total follow-up in both groups (45.0 vs. 9.1%, log-rank P = 0.014 in RHD group; 64.5 vs. 43.8%, log-rank P = 0.001 in control group).

conclusionsThe long-term outcome of RFCA for AF in RHD patients with mild MS was mediocre and worse than that for AF patients without RHD. The severity of MR was associated with RFCA outcome in both groups. In RHD patients with mild MS, a better prognosis of paroxysmal AF than non-paroxysmal AF was observed initially but turned similar over time.
