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: Malignant brain tumors emphasize the importance of O-(2- Methods: A total of 62 patients performing brain Results: PET reconstruction images at 15, 17, and 20 minutes were considered to provide diagnostic value. The mean standardized uptake value (SUV) and tumor-to-brain ratio (TBR) showed minimal variation with acquisition duration for all three algorithms, with the relative percentage difference (RPD) <1.2% after 
15 minutes. The maximum SUV (SUVmax), maximum TBR (TBRmax), metabolic tumor volume (MTV), and total lesion uptake (TLU) became usable when acquisition time exceeded 15 minutes, with an RPD of around 5% or less. There were 8 common metabolic features and 30 radiomics features which demonstrated excellent repeatability between the three algorithms at 15, 17, and 20 minutes. The HIWT algorithm identified 18 stable radiomics features, whereas the OWT identified 2, and the OSEM identified 3. Conclusions: This study offers a reference for clinically reducing the acquisition time of
