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

Introduction: Enfortumab vedotin plus pembrolizumab has emerged as a standard first-line therapy for advanced urothelial carcinoma (UC). However, pseudoprogression during this combination remains poorly characterized. Case Presentation: A 71-year-old man with muscle-invasive bladder cancer and lymph node metastasis received enfortumab vedotin plus pembrolizumab. During treatment, imaging suggested tumor progression with new hydronephrosis. Repeat transurethral resection revealed no viable tumor. Because of persistent symptoms, robot-assisted radical cystectomy was performed. Histopathological examination demonstrated no residual tumor cells, indicating pathological complete response (ypT0N0), with prominent CD8- and CD4-positive T-cell infiltration and minimal CD20-positive B-cell infiltration. Conclusion: This case suggests that pseudoprogression may occur during enfortumab vedotin plus pembrolizumab therapy. Careful interpretation of radiological findings is essential to avoid premature treatment discontinuation.
