1 · What the graph read from 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.

2 · The registry

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

Background: During computed tomography pulmonary angiography (CTPA) examination, contrast accumulation in the superior vena cava often generates beam hardening artifacts (BHAs), which can interfere with accurate diagnosis. This study aimed to investigate the diagnostic value of dual-energy computed tomography (DECT) quantitative parameters in differentiating pulmonary embolism (PE) from BHA. Methods: A total of 68 patients with PE who underwent DE-CTPA were retrospectively included. Quantitative parameters [slope of Hounsfield unit (HU) curves (Slope), CT values on virtual monoenergetic images (VMIs) ranging from 40 to 100 keV (HU Results: Quantitative parameters, including HU Conclusions: Quantitative parameters derived from DECT could recognize BHA in the superior vena cava; therein, 90 keV and 100 keV VMIs and their HU measurements would be particularly valuable.
