Not just about weight: Identifying hidden nutritional vulnerability after radical cystectomy.
Observational study in European journal of clinical nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Patients undergoing radical cystectomy face substantial nutritional challenges, yet dietary intake patterns and their adequacy remain poorly defined. In this prospective observational study of 25 ERAS-managed patients, energy and protein adequacy was low during the first postoperative week, while body weight remained stable - likely influenced by fluid retention. Significant weight loss emerged by day 14 (-2.3%; p < 0.001), which increased by day 30 (-5.3%; p < 0.001), despite dietetic follow-up and improvements in dietary intake. Patients requiring nasogastric decompression experienced greater weight loss than those without (-7.2% vs. -3.9%; p = 0.004), suggesting an association with nutritional deterioration. We conclude that early weight trajectory alone may not be a good indicator of nutritional status. Evaluating dietary intake, nutritional symptoms, and body composition including fluid balance is likely required for optimal clinical decision-making. This underscores the importance of individualized, symptom-responsive strategies, including consideration of supplemental nutrition in patients with persistent intolerance.
