Reconsidering palliative radiotherapy in addition to PD-1 blockade for non-small cell lung cancer: results from the FORCE phase II trial (AIO/YMO-TRK-0415).
Trial report in Clinical & experimental metastasis, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03044626 (Fostering Efficacy of Anti - PD-1 - Treatment), which is not on this map. Cited by 4 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.

Abstract
Introduction of immune checkpoint inhibitors (ICI) has improved overall survival (OS) for advanced non-small cell lung cancer (NSCLC). However, responses differ greatly amongst patients. Additional radiotherapy (RT) may promote tumor-specific immunity and synergize with ICI to improve tumor control. The multicenter phase II FORCE trial evaluated safety and efficacy of nivolumab with additional palliative radiotherapy (5 × 4 Gy) as clinically indicated in pre-treated metastatic non-squamous NSCLC (group A, n = 41), including pretreated patients without an indication for radiotherapy in a parallel cohort as real-world controls (group B, n = 60). With an objective response rate (ORR) of 8.3% in group A (n = 41), the primary endpoint was not met (p = 0.991). ORR in group B (n = 60) was 23.8%. Patient characteristics indicated a significantly poorer baseline clinical condition for group A compared to B, including worse Eastern Cooperative Oncology Group (ECOG) performance status (PS, p = 0.020) and more metastatic sites (p = 0.009). Consequently, group A had shorter progression-free survival (median PFS, 1.9 versus 3.7 months, hazard ratio [HR] 1.69 [95% CI (1.10, 2.58)]) and OS (median 6.0 versus 12.6 months, HR 1.75 [95% CI (1.07, 2.84)]). In multivariable analyses for the intention-to-treat (ITT) population, ORR, PFS and OS were inversely associated with the patients' ECOG PS (ORR odds ratio [OR] 0.126, p = 0.004) and correlated positively with tumor PD-L1 expression (ORR OR 12.8, p = 0.022), but not with radiotherapy administration (p = 0.169-0.854). Adverse events were distributed equally in both groups. Addition of palliative radiotherapy to nivolumab was safe and feasible, but not associated with improved efficacy. Patients with an indication for palliative radiotherapy have an inherently worse prognosis which cannot be overcome by radiation-induced immunostimulation. Clinical features and PD-L1 expression influence clinical outcomes more than radiotherapy administration and should be considered when evaluating the effectiveness of immuno-/radiotherapy combinations.ClinicalTrials.gov identifier: NCT03044626.
