Development and validation of a CXCR4-targeted
Article in European journal of nuclear medicine and molecular imaging, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposePrimary aldosteronism represents the most common and treatable form of secondary hypertension. Although over 90% of patients achieve resolution of hypokalemia post-operatively, nearly half still require antihypertensive medications. This study aimed to develop and validate a nomogram integrating preoperative clinical characteristics and CXCR4 targeted 68 Ga-Pentixafor PET/CT parameters to predict postoperative clinical outcomes in UPA.
methodsA total of 109 UPA patients underwent adrenalectomy were retrospectively collected with preoperative 68 Ga-Pentixafor PET/CT parameters, clinical data and surgical outcomes at 6 months. Predictors identified by backward stepwise regression were incorporated into a nomogram based on the Akaike information criterion (AIC). Model performance was evaluated using receiver operating characteristic (ROC) curves, calibration plots, decision curve analysis (DCA), and multi-model comparison. Risk stratification was further performed to explore the model’s clinical applicability.
resultsAmong 109 patients, 64 (58.7%) achieved complete clinical success. Six presurgical predictors (age, duration of hypertension, LLR R, SULmax R, LI2 R, and SULmean) were included in the final model. The model demonstrated excellent discrimination (AUC 0.90, 95% CI 0.83–0.97 in the training cohort; 0.80, 95% CI 0.62–0.97 in the validation cohort) with good calibration and significant clinical net benefit. Risk stratification further revealed clear gradient separation and strong clinical feasibility.
conclusionThe proposed nomogram combining clinical and 68 Ga-Pentixafor PET/CT parameters serves as a robust preoperative tool for accurately distinguishing patients who will achieve complete clinical success after adrenalectomy from those requiring ongoing antihypertensive therapy.
