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
backgroundIdentifying patients at increased risk of recurrence of acute pericarditis remains challenging. High-sensitivity C-reactive protein (hs-CRP) can be used to predict recurrence, but it has certain limitations.
objectivesThis study aimed to evaluate the association between a novel biomarker, the Systemic Immune-Inflammation Index (SII), and the recurrence of acute pericarditis.
methodsThis retrospective cohort study included 110 patients diagnosed with acute idiopathic pericarditis, the primary endpoint of the study was to investigate Recurrent Pericarditis (RP) during the 18 month follow-up period. Patients were divided into two groups based on whether or not they developed recurrent pericarditis. Physical examination, electrocardiography, echocardiography, and laboratory test results of these patients were evaluated. P < 0.05 was considered statistically significant.
resultsThe mean age of the patients was 42.8 ± 15.2 years, and 42.7% were male. The group with RP had significantly higher leukocyte counts (8.7 ± 3.2 vs. 12 ± 4.7; p = 0.001), neutrophil counts (5.4 ± 2.7 vs. 9 ± 4.5; p < 0.001), hs-CRP levels (29.1 ± 40.9 vs. 49.5 ± 62.2; p = 0.048), and neutrophil-to-lymphocyte ratio (2.9 ± 2.5 vs. 6 ± 2.8; p < 0.001). SII (783.2 ± 770.2 vs. 1664.2 ± 1086.6; p < 0.001) was also significantly higher in patients with recurrence. Both SII and hs-CRP were independently associated with recurrence (p < 0.001 and p < 0.05, respectively).
conclusionSII and hs-CRP were found to be independent predictors for recurrence in acute pericarditis patients during the 18 month follow-up. Similar to hs-CRP, SII may also be used as an important parameter in predicting recurrent pericarditis.
