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

Background: Chronic kidney disease (CKD) affects 843 million people worldwide yet remains underdiagnosed. Current risk stratification, including the CKD Prognosis Consortium (CKD-PC) score, relies on laboratory data rarely evaluated outside nephrology settings. Chest radiographs (CXR) are among the most frequently performed imaging procedures globally, offering an opportunistic screening pathway. CXR-CKD5, a CXR-derived AI score for predicting 5-year incident CKD without laboratory data, was developed and externally validated. Methods: In this retrospective two-centre study conducted at two sites in the USA, 97,553 adults (≥18 years) without baseline CKD who underwent routine CXR were included: Emory University (development cohort, 2008-2021, n = 75,683) and University of Illinois Chicago (external validation cohort, 2010-2020, n = 21,870). Patients with a CKD diagnosis within 90 days of the index CXR were excluded. A convolutional neural network extracted 10 cardiopulmonary and metabolic risk features from routine CXRs, which were used to train an XGBoost accelerated failure time model. The primary outcome was 5-year incident CKD. Discrimination (C-index) and calibration were evaluated against a clinical base model and the CKD-PC score. Findings: CXR-CKD5 achieved apparent C-indices of 0.774 (95% CI: 0.768-0.780) in development (optimism-corrected: 0.737) and 0.713 (95% CI: 0.697-0.729) at external validation. A combined imaging-clinical model achieved the highest external validation discrimination (C-index 0.734, 95% CI: 0.719-0.751). Performance was strongest in non-diabetic patients (development C-index 0.783, 95% CI: 0.775-0.790; external validation 0.714, 95% CI: 0.689-0.739) and attenuated in diabetic patients across both cohorts (development C-index 0.658, 95% CI: 0.645-0.671; external validation 0.607, 95% CI: 0.580-0.634). Absolute risk was overestimated at external validation, indicating that calibration would be required before deployment at new institutions. A threshold of ≥15% predicted risk identified the top 20% at risk. Interpretation: CXR-CKD5 demonstrates that routine chest radiographs can identify patients at elevated CKD risk without laboratory data, offering a scalable opportunistic screening pathway. Recalibration and prospective evaluation assessing clinical outcomes and workflow integration are needed before deployment.
