Comparison of DLIR-H and ASIR algorithms for image reconstruction in low-dose chest CT of pediatric mycoplasma pneumoniae pneumonia: a cross-sectional study.
Article in Translational pediatrics, 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
Background: Pediatric Methods: In this retrospective cross-sectional study, consecutive pediatric patients who underwent low-dose chest CT (September 2023-March 2024) who were positive for MP-IgM and negative for other respiratory pathogen antibodies were included; patients with incomplete data, poor scan cooperation or a body mass index (BMI) ≥25 kg/m Results: Among the 235 screened patients, 142 (77 males and 65 females) were included (8.427±3.706 years), with a mean BMI of 16.19±1.83 kg/m Conclusions: DLIR-H outperforms ASIR variants in low-dose pediatric chest CT, with minimal background noise, the highest lesion CNR and the best subjective quality at a clinically low effective dose, enhancing radiologists' diagnostic confidence and balancing radiation safety with imaging quality. Limitations include the retrospective design, DLIR-H's inferior lung parenchyma SNR, GE-only equipment compatibility, and unassessed MPP diagnostic accuracy. Prospective multicentre validation is required for broader clinical translation.
