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
purposeTo investigate the feasibility of using CT combined with injury factors to predict the lethality and severity of primary blast lung injury through establishing a goat model simulating real explosion effects.
methodsHigh explosives were detonated at two altitudes in natural fields, with goats positioned at distances of 2 to 6 meters from the explosion center, facing either the right side or the front chest. CT features and quantitative data post-injury were recorded, along with blood gas analysis in surviving goats and lung coefficient measurements. Correlation analysis between CT severity score and lung coefficient was performed. ROC curve analysis was conducted to evaluate the multi-factors in distinguishing severity (severe/serious vs. moderate/slight) and lethality (death vs. survival). Nomograms based on injury factors and CT were developed to predict the risk of severe/serious injury and death.
resultsAfter the experiment, a total of 87 goats were classified as severe/serious lung injury through pathology, including 40 goats that died on the spot. High altitude, close distance, and right-side orientation exacerbated lung injury severity, with close distance being the primary cause of death. Lung coefficient, CT score, and volume exhibited excellent performance in distinguishing outcomes (AUC: 0.967, 0.925, and 0.924 for lethality; 0.944, 0.915, and 0.909 for severity, respectively), with no significant difference in diagnostic efficacy. Moderate correlations were observed between lung coefficient and CT score for severity (r=0.440; 0.480), with a strong correlation for survival but none for death. Volume emerged as the primary risk factor, and the nomograms incorporating multiple factors demonstrated personalized predictive abilities.
conclusionCT combined with altitude, distance, and orientation can effectively predict the lethality and severity of primary blast lung injury, providing significant value for accurate injury assessment and clinical management.
