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

objectiveTo investigate the expression patterns of Nectin-4, the target molecule of the antibody-drug conjugate enfortumab vedotin (EV), in relation to histological and molecular subtypes of urothelial bladder cancer (UBC). PATIENTS AND

methodsWe assessed the protein expression patterns of Nectin-4 in a spatially organised tissue microarray containing 1386 tissue cores from 314 consecutive patients with UBC who underwent radical cystectomy (2005-2018). Results were correlated with clinicopathological and follow-up data, as well as with different spatial locations (tumour central vs tumour-normal interface and primary tumour vs lymph node [LN] metastases). Additionally, we correlated Nectin-4 expression levels with histological and molecular subtypes. Finally, we assessed the value of Nectin-4 expression for predicting the efficacy of platinum therapy in the peri-operative setting.

resultsNectin-4 expression was observed in 63% of primary tumours and 87% of LN metastases, with significantly higher levels in LNs. Of the histological subtypes, the micropapillary (58%) and pure urothelial histologies (30%) were associated with the highest Nectin-4 positivity, while the sarcomatoid (17%), squamous (15%) and small/cell-neuroendocrine (0%) subtypes exhibited the lowest. Nectin-4 immunopositivity rates were significantly higher in luminal (urothelial-like [42%] and genomically unstable [34%] Lund subtypes) compared to the basal (5%) or mesenchymal (0%) molecular subtypes. Higher Nectin-4 expression levels were associated with lower tumour stage but showed no association with overall survival. Finally, patients with low Nectin-4 expression tended to derive more benefit from platinum-based chemotherapy in both adjuvant and neoadjuvant settings (P < 0.001, P = 0.067).

conclusionOur results revealed a low spatial heterogeneity of Nectin-4 expression within the primary tumour. In contrast, differential Nectin-4 expression was found in the context of histological and molecular subtypes. Nectin-4-expressing tumours may show varying sensitivity to both EV and platinum-based chemotherapy.
