A novel Seizure Quality Index based on ictal parameters for optimizing clinical decision making in electroconvulsive therapy. Part 1: development.
Observational study in European archives of psychiatry and clinical neuroscience, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers, 1 of them a synthesis that pooled 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.
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
Early identification of patients at high risk for an unfavorable outcome to ECT during the course might be beneficial because it provides an opportunity for timely intensification or optimization of stimulus conditions. We aimed to develop a new Seizure Quality Index (SQI) that delivers a clinical relevant outcome prediction early in the treatment course and can be used within common clinical setting. An observational study was conducted. Patients (n = 86) with a depressive episode and the clinical decision for ECT (right unilateral, brief pulse) were included, and several ictal parameters derived from the second ECT session and the clinical outcome of the patients were documented. Optimal cut-off points for five different domains of ictal adequacy for younger and older patients for the prediction of "non-response" and "non-remission" based on seizure quality was determined by the Youden Index and a sum score was built. Logistic regression analyses tested the predictive power of derived models. For both outcome variables "non-response" and "non-remission", the logistic regression models were statistically significant, albeit for remission only for subjects below the age of 65 years (χ
