Transthyretin Cardiac Amyloidosis in a Very Elderly Patient With a History of Inferior Myocardial Infarction: A Case Report.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Transthyretin cardiac amyloidosis (ATTR-CA) involves the buildup of transthyretin protein in the heart muscle in the form of amyloid fibrils, which can affect heart structure and function. Common ECG findings of ATTR-CA include low QRS voltage and a pseudo-myocardial infarction (MI) pattern, defined as pathological Q waves or QS complexes in two consecutive leads without a history of MI or echocardiographic evidence of akinetic areas. Here, we present a case of ATTR-CA in a very elderly patient, in whom pathological Q waves on ECG were true indicators of a prior inferior MI. A 96-year-old woman with a history of inferior MI presented to her primary care clinic with a one-week history of nocturnal dyspnea. She had undergone coronary stent placement in the distal right coronary artery five years earlier for inferior MI. An ECG revealed abnormal Q waves, ST elevation of 0.5 mm, and T wave inversion in limb leads III and aV
