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
Introduction: This study was designed to validate the formula of New Baseline Glomerular Filtration Rate (NB-GFR) within a multicenter cohort of southern Chinese patients who underwent radical nephrectomy (RN) or partial nephrectomy (PN), with a specific focus on assessing its accuracy and effectiveness. Methods: The predictive capability of the formula proposed by professor Palacios DA for estimating NB-GFR after PN or RN was evaluated, with a focus on its efficacy in the southern Chinese population. A retrospective analysis was conducted involving 398 RN patients and 185 PN patients from three hospitals between 2015 and 2022. The correlation between the postoperative NB-GFR predicted by the equation and the actual GFR of the patients was analyzed, and the level of agreement was assessed. Results: We found strong positive correlation between NB-GFR and GFR after PN, with a correlation coefficient of R = 0.645, 95% confidence interval (95% confidence interval (CI)) [0.552-0.722], Conclusion: The NB-GFR prediction equation demonstrates moderate concordance with actual postoperative GFR in southern Chinese patients undergoing RN or PN, indicating broad application potential.
