The density histograms-derived computerized integrated index (CII) predicts mortality in idiopathic pulmonary fibrosis.
Article in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Quantitative assessment of the extent of radiological alterations in interstitial lung diseases is a promising field of application that goes beyond the limitations of qualitative scoring. Analysis of density histograms, i.e., skewness, kurtosis, and mean lung attenuation, is among the most studied approaches. We recently proposed their integration in a single parameter, the computerized integrated index (CII), to reduce their redundancy. The CII has proven effective in detecting subclinical lung involvement, correlates with lung function/disease activity, and predicts mortality in systemic sclerosis patients. Seventy-three newly diagnosed and therapy-naive IPF patients (M = 50; median age: 70.2 years) were prospectively enrolled from January 2014 to December 2022, and followed till December 2023. At baseline, all underwent lung function testing and volumetric high resolution chest CT. Density histograms were analyzed with an open-source automatic platform (Slicer 3D) and CII derived by means of Principal Component Analysis, as previously described. During a median follow-up of 5.8 years, 39 (53.4%) subjects died. Median overall survival (OS) was 4.9 years (95% CI 3.7 years-not estimable). The CII was significantly associated with OS (HR 0.49; 95% CI 0.35-0.68; P < 0.001) and correlated with lung function (r = 0.41; 95% CI 0.19 to 0.60; P < 0.001 for FVC, and r = 0.62; 95% CI 0.44 to 0.75; P < 0.001 for DLCO
