Comparison of the Efficacy and Safety of PD-1/PD-L1 Inhibitors in the Treatment of Small Cell Lung Cancer.
Article in Cancer reports (Hoboken, N.J.), 2025. 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
objectiveThis study aims to evaluate the efficacy and safety of PD-1/PD-L1 inhibitors in treating small-cell lung cancer (SCLC) and determine the role of PD-1 monoclonal antibodies in improving patient outcomes.
methodsA retrospective analysis was performed on 37 SCLC patients who received PD-1 or PD-L1 inhibitors along with chemotherapy at the First Hospital of Lanzhou University between June 2018 and June 2023. Treatment effectiveness was measured by overall response rate (ORR), disease control rate (DCR), overall survival (OS), and progression-free survival (PFS), utilizing chi-square and T-tests, along with Kaplan-Meier and log-rank analyses.
resultsIn the PD-L1 group, 16 patients achieved partial or complete response, versus 12 in the PD-1 group, though the difference in the ORR was not statistically significant (50.0% vs. 36.8%, p = 0.308). Median survival times were 21.0 months for PD-L1 and 17.0 months for PD-1, with no statistically meaningful difference (p = 0.180). Adverse effects were comparable between the groups in terms of thyroid function (p = 0.898), but bone marrow suppression and gastrointestinal reactions were significantly less severe in the PD-L1 group (p = 0.047 and p = 0.002).
conclusionImmunotherapy combined with chemotherapy offers significant benefits for advanced SCLC patients, irrespective of the type of inhibitor used. Despite the higher incidence of adverse reactions with PD-1 inhibitors, they remain a viable option, particularly when PD-L1 inhibitors are not available, due to their manageable safety profile and effective response.
