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
introductionTranscatheter aortic valve implantation (TAVI) is an alternative to surgical aortic valve replacement (SAVR) in patients with increased comorbidity. Lead aVR in surface ECG has valuable information about prediction of mortality in many cardiovascular diseases. Our aim was to determine the relationship between ischemic changes in lead aVR and mortality in TAVI patients. MATERIAL AND
methodsWe retrospectively examined 86 patients with TAVI. The ST segment deviation in lead aVR (STaVR) and T wave polarity (TPaVR) on surface ECG were measured. The absolute values of TPaVR and STaVR were calculated. A ratio (TP/STaVR or vice versa) was obtained from the division of the larger absolute value by the smaller one.
resultsThe patients were divided into two groups as living and deceased. The living group had 68 patients, and the deceased group had 18 patients. The number of positive TPaVR patients after TAVI, TPaVR after TAVI, and TP/STaVR ratio after TAVI were significantly higher in the deceased group. The deceased group had a significantly shorter aortic annulus-LMCA distance. Presence of positive TPaVR (OR = 8.765, 95% CI: 1.088-70.618,
conclusionsIschemic changes in lead aVR may provide valuable information about mortality after TAVI.
