Seasonal patterns of acute and recurrent idiopathic pericarditis.
Article in Clinical cardiology, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
backgroundIdiopathic pericarditis is presumed to result from viral infection. The incidence rates of some viral infections have typical seasonal patterns. The data in the literature on a possible seasonal pattern of acute pericarditis are very limited. The mechanism and possible seasonality of recurrent episodes are not well established . HYPOTHESIS: The incidence of acute idiopathic pericarditis has a seasonal pattern.
methodsThe computerized database of a tertiary, university-affiliated hospital was searched for all patients admitted with a first episode of acute idiopathic pericarditis between January 1, 2010 and December 31, 2015. Patients for whom a nonviral etiology for the pericarditis was identified were excluded.
resultsThe final cohort included 175 patients (75% male) ages 19 to 86 years (median = 50.0 ± 18.2 years). The incidence of the disease was twice as high during the colder half of the year (October-March) than the warmer half, peaking in the first quarter (January-March, P = 0.001). This first-quarter peak was observed in each of the 6 years examined. Comparison of the patients who acquired pericarditis during peak and nonpeak quarters yielded no differences in baseline characteristics, peak body temperature, white blood cell count, C-reactive protein level, or frequency of myocardial involvement or liver enzyme elevation. No seasonal pattern was identified for recurrent episodes of pericarditis (n = 57).
conclusionsAcute idiopathic pericarditis appears to have a seasonal pattern with a distinct late winter peak. No seasonal pattern was identified for recurrent episodes.
