Early Tumor Shrinkage as a Predictor of Favorable Treatment Outcomes in Patients With Extensive-Stage SCLC Who Received Programmed Cell Death-Ligand 1 Inhibitor Plus Platinum-Etoposide Chemotherapy: A Prospective Observational Study.
Article in JTO clinical and research reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Introduction: In recent years, programmed cell death-ligand 1 (PD-L1) inhibitor plus platinum-etoposide chemotherapy was found to have favorable clinical outcomes in patients with extensive-stage SCLC (ES-SCLC). The usefulness of early tumor shrinkage (ETS) has been reported in various types of cancers. Nevertheless, there have been few reports evaluating ETS in ES-SCLC. Therefore, this study aimed to evaluate the role of ETS in the clinical outcomes of patients with ES-SCLC receiving chemoimmunotherapy. Methods: We prospectively identified 46 patients with ES-SCLC who received PD-L1 inhibitor plus platinum-etoposide chemotherapy at 10 institutions in Japan between September 2019 and October 2021. Of them, 35 patients were selected for analyses. Results: The responders (progression-free survival [PFS] ≥ 6.0 mo) had significantly greater tumor shrinkage at the first evaluation than the nonresponders (PFS < 6.0 mo) (65.0% versus 53.7%, Conclusions: Our prospective observational study indicated that ETS was related to favorable clinical outcomes for patients with ES-SCLC receiving PD-L1 inhibitor plus platinum-etoposide chemotherapy.
