Comparison of the efficacy of spiral CT combined with advanced multiplanar reconstruction in detecting the progression of pneumoconiosis.
Article in Frontiers in medicine, 2026. 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
Objective: To investigate the value of multiplanar reconstruction (MPR) technology in the quantitative analysis of bronchovascular bundle (BVB) for staging pneumoconiosis. Methods: We retrospectively analyzed CT data from 65 patients with confirmed pneumoconiosis (42 stage I, 16 stage II, 7 stage III) at Hefei Third People's Hospital between January 2020 and March 2025. MPR was used to measure the bronchial wall thickness-to-diameter ratio (WT/D), the vascular bifurcation angle variation index (AVI), and the peribronchial fractal dimension (FD). Feature parameters were selected using Lasso regression, and diagnostic efficacy was evaluated using ROC curves. Results: Significant intergroup differences were observed: the stage III group showed significantly higher WT/D, AVI, and FD values than the stage I group ( Conclusion: MPR technology can quantify structural distortions of the BVB in pneumoconiosis. The combined parameter model provides an objective imaging basis for the clinical staging of pneumoconiosis.
