Sequencing of PD-1/L1 Inhibitors and Carboplatin Based Chemotherapy for Cisplatin Ineligible Metastatic Urothelial Carcinoma.
Article in The Journal of urology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeCurrent first line treatment options in patients with metastatic urothelial carcinoma unfit to receive cisplatin containing chemotherapy include PD-1/L1 inhibitors and carboplatin containing chemotherapy. However, the optimal sequencing of these therapies remains unclear. MATERIALS AND
methodsWe conducted a multicenter retrospective analysis. Consecutive cisplatin ineligible patients with metastatic urothelial carcinoma treated with first line carboplatin containing chemotherapy followed sequentially by second line PD-1/L1 inhibitor, or the reverse order, were included. Patient demographics, objective response, time to treatment failure for first line and second line therapy, interval between end of first line and initiation of second line treatment (Interval
resultsIn this multicenter retrospective study we identified 146 cisplatin ineligible patients with metastatic urothelial carcinoma treated with first line PD-1/L1 inhibitor therapy followed by second line carboplatin containing chemotherapy (group 1, 43) or the reverse sequence (group 2, 103). In the overall cohort median age was 72, 76% were men and 18% had liver metastasis. In both groups objective response rates were higher with carboplatin containing chemotherapy (45.6% first line, 44.2% second line) compared to PD-1/L1 inhibitors (9.3% first line, 21.3% second line). On multivariate analysis treatment sequence was not associated with overall survival (HR 1.05, p=0.85). Site of metastasis was the only factor significantly associated with overall survival (p=0.002).
conclusionsIn this biomarker unselected cohort of cisplatin ineligible patients with metastatic urothelial carcinoma, PD-1/L1 inhibitor followed by carboplatin containing chemotherapy and the reverse sequence had comparable overall survival.
