Article in Epilepsy currents. 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
Blood Markers of Cardiac Stress After Generalized Convulsive Seizures. Nass RD, Motloch LJ, Paar V, Lichtenauer M, Baumann J, Zur B, Hoppe UC, Holdenrieder S, Elger CE, Surges R.
methodsAdult patients with refractory epilepsy who underwent video-electroencephalography monitoring along with simultaneous one-lead electrocardiography recordings were included. Cardiac biomarkers (cardiac troponin I [cTNI]; high-sensitivity troponin T [hsTNT]; N-terminal prohormone of brain natriuretic peptide; copeptin; suppression of tumorigenicity-2 [SST-2]; growth differentiation factor 15, [GDF-15]; soluble urokinase plasminogen activator receptor [suPAR]; and heart-type fatty acid binding protein [HFABP]) and catecholamines were measured at inclusion and at different time points after GCS. Peri-ictal cardiac properties were assessed by analyzing heart rate (HR), HR variability (HRV), and corrected QT intervals (QTc).
resultsThirty-six GCS (6 generalized-onset tonic-clonic seizures and 30 focal to bilateral tonic-clonic seizures) were recorded in 30 patients without a history of cardiac or renal disease. Postictal catecholamine levels were elevated more than 2-fold. A concomitant increase in HR and QTc, as well as a decrease in HRV, was observed. Elevations of cTNI and hsTNT were found in 3 (10%) of 30 patients and 6 (26%) of 23 patients, respectively, which were associated with higher dopamine levels. Copeptin was increased considerably after most GCS, whereas SST-2, HFABP, and GDF-15 displayed only subtle variations, and suPAR was unaltered in the postictal period. Cardiac symptoms did not occur in any patient. SIGNIFICANCE: The use of more sensitive biomarkers such as hsTNT suggests that signs of cardiac stress occur in about 25% of the patients with GCS without apparent clinical symptoms. Soluble urokinase plasminogen activator receptor may indicate clinically relevant troponin elevations. Copeptin could help to diagnose GCS but specificity needs to be tested.
