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

BACKGROUND/

aimTo clarify the clinical significance of the temporary elevated C-reactive protein (CRP) levels followed by a decrease below baseline (CRP flare response) after administration of pembrolizumab to patients with advanced urothelial carcinoma (UC). PATIENTS AND

methodsWe retrospectively reviewed 31 patients with advanced UC who received pembrolizumab. Patients were categorized into 3 groups (flare-responder, responder, non-responder) according to early CRP kinetics. Intergroup tumor response and survivals were compared.

resultsObjective response rates of flare-responder, responder, and non-responder groups were 75%, 80%, and 26%, respectively. Median overall survival was not reached in flare-responder and responder groups, and was 10.2 months in the non-responder group (p=0.03). Furthermore, the flare-responder group did not reach median progression-free survival, and for the responder and non-responder groups it was 15.2 and 2.8 months, respectively (p=0.03).

conclusionCRP flare response might be a promising biomarker in patients with advanced UC who received pembrolizumab.
