Antiangiogenic therapy combined with immune checkpoint blockade in urothelial cancer: Systematic review and meta-analysis.
Article in Bladder cancer (Amsterdam, Netherlands), 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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: Antiangiogenic therapy had been tested in urothelial cancer (UC) without reaching the clinic. Objective: We provide a systematic review and meta-analysis of trials to assess efficacy of immune checkpoint inhibitors (ICI) combined with antiangiogenic agents in UC. Methods: Following PRISMA guidelines, we searched for trials with at least one arm of patients with UC treated with ICI plus antiangiogenics. Data were analyzed with the "meta" package from R using a one-staged frequentist meta-analysis. Results: After screening 13,708 titles and abstracts, 9 studies were selected for analysis with 14 identified cohorts comprising 621 patients: 448 were ICI-naïve (ICI-N) and 173 were ICI-exposed (ICI-E). The estimated objective response rate (ORR) in all patients was 27% (21-35). In the ICI-N group, ORR was 34% (28-41). Conversely, the ICI-E group had a lower ORR of 16% (9-28). This difference was mainly driven by a higher partial response rate of 27% (23-31) in ICI-N group compared to 13% (8-20) in the ICI-E group. Disease control rate was 72% (66-77) ICI-N group vs. 71% (64-78) in ICI-E group. Median overall survival ranged from 6.4 to 24.9 months in the ICI-N group, and 8.2 to 10.4 months in ICI-E group. Median progression free survival ranged from 1.9 to 10.1 months and from 3 to 3.9 months in both groups, respectively. Conclusion: ORR with ICI plus antiangiogenics was lower after prior ICI exposure, with substantial variability estimates among included trials, either due to differences among antiangiogenic agents used or trial-related factors. Future exploration of ICI combined with antiangiogenics in UC, especially in ICI-refractory setting, will benefit from better patient selection.
