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
backgroundHeart failure (HF) and chronic kidney disease (CKD) are common comorbidities among patients undergoing coronary angiography. Both conditions are associated with increased risk of adverse cardiovascular outcomes and mortality. However, the joint prognostic impact of HF and CKD in this patient population remains unclear.
aimsWe aimed to evaluate the separate and combined associations of HF and CKD with all-cause mortality in patients undergoing coronary angiography.
methodsWe analyzed data from the KARDIO registry, an ongoing real-life clinical database of patients undergoing coronary angiography. Multivariable Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for all-cause mortality.
resultsOver a median follow-up of 5.5 years, 11,896 all-cause deaths were recorded. In multivariable-adjusted analyses, a history of HF was associated with a higher risk of mortality compared to no HF (HR: 2.19; 95% CI: 2.04-2.34), as was a history of CKD compared to no CKD (HR: 2.06; 95% CI: 1.94-2.19). The associations persisted on mutual adjustment for each exposure. When assessed jointly, and using patients with neither condition (No HF-No CKD) as the reference group, the adjusted HRs (95% CI) for mortality were 2.18 (2.01-2.36) for HF only, 2.04 (1.90-2.20) for CKD only, and 3.09 (2.77-3.46) for patients with both HF and CKD. Interaction analyses revealed that the associations of HF and CKD with mortality were significantly modified by each other, with the highest risk observed among individuals with both conditions. Subgroup analyses showed consistent directions of association across most categories, although the prognostic impact of HF and CKD varied by age, sex, and cardiovascular disease history.
conclusionsIn patients undergoing coronary angiography, HF and CKD were each independently associated with a twofold increased risk of all-cause mortality. Interaction effects suggest that the co-occurrence of HF and CKD synergistically amplifies this risk. These findings highlight the importance of identifying and managing cardiorenal comorbidity to improve outcomes in this high-risk population.
