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

Purpose: To investigate the performance of chest photon-counting CT (PCCT) at low-dose (LD) and ultralow-dose (ULD) in young musculoskeletal malignancy patients with pulmonary metastasis and compare with prior standard-dose energy-integrating CT (EICT). Materials and methods: From August to November 2023, this prospective study recruited consecutive participants with prior EICT images and grouped them into LD and ULD groups to receive PCCT examination. Two observers independently and blindly evaluated the image quality using a five-point Likert scale. Intraindividual differences between PCCT and EICT were compared using the Wilcoxon signed-rank test or paired samples Results: The LD and ULD groups included 50 (19 [16; 21] years; 33 males) and 50 participants (19 [14; 21] years; 30 males), respectively. The interval between EICT and PCCT examinations was 116 (88.5; 194) days. Compared with EICT, PCCT obtained median effective dose reduction rates of 87.62 % (3.78 [3.15; 5.18] vs. 0.43 [0.39; 0.58] mSv; Conclusion: PCCT provided higher image quality and lung nodule visualization with significant dose reduction compared to EICT in these young musculoskeletal malignancy patients.
