Tei Index Complements Conventional Echocardiographic Parameters in Diagnostic Workup of Suspected Takotsubo Syndrome.
Article in Medical principles and practice : international journal of the Kuwait University, Health Science Centre, 2023. 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
backgroundTei index (TI) is a combined myocardial performance index for overall cardiac function, the sensitivity of which seems to be better than that of systolic and diastolic parameters alone. Evidence for TI in the context of Takotsubo syndrome (TTS) is currently limited, which is why we chose to investigate this parameter in affected patients. SUBJECTS AND
methodsPatients with TTS (n = 51), acute coronary syndrome (ACS; n = 29), and controls (n = 58) were retrospectively investigated. Laboratory and echocardiographic parameters including TI were analyzed for their ability to discriminate TTS in the total study cohort.
resultsTI was the highest, and thus most pathological, in patients with TTS (median 0.516 vs. ACS: 0.355 vs. control: 0.313, p < 0.0001) and showed the best discriminatory ability for TTS (AUC: 0.836, p < 0.0001). A cut-off for diagnosis of TTS was calculated at ≥0.418 (specificity: 83.5% and sensitivity: 74.0%) by means of the Youden index.
conclusionThe discriminatory ability of TI was better than that of other echocardiographic parameters such as LV systolic function. Due to the simple, fast, and inexpensive way of calculating TI, diagnostic workup with conventional parameters could be complemented by TI in patients with suspected TTS.
