Tiragolumab Plus Atezolizumab and Chemotherapy for Advanced Nonsquamous Non-Small Cell Lung Cancer: The Phase 3 SKYSCRAPER-06 Randomized Clinical Trial.
Trial report in JAMA oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04619797 (A Phase II/III, Randomized, Double-Blind, Placebo-Controlled Study of Tiragolumab in Combination With Atezolizumab Plus Pemetrexed and Carboplatin/Cisplatin Versus Pembrolizumab Plus Pemetrexed and Carboplatin/Cisplatin in Patients With Previously Untreated Advanced Non-Squamous Non-Small-Cell Lung Cancer), which is not on this map.

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

Abstract
Importance: Programmed cell death 1 ligand 1/programmed cell death protein 1 inhibitors, with or without chemotherapy, are standard first-line treatment for patients with advanced non-small cell lung cancer (NSCLC); however, survival benefit is limited, and many patients experience disease progression. Objective: To evaluate the efficacy and safety of tiragolumab plus atezolizumab plus chemotherapy vs placebo plus pembrolizumab plus chemotherapy in patients with advanced nonsquamous NSCLC. Design, Setting, and Participants: SKYSCRAPER-06 was a phase 3 randomized clinical trial that recruited patients with previously untreated, locally advanced unresectable or metastatic NSCLC at 129 sites in 21 countries between December 15, 2020, and September 14, 2023 (data cutoff, April 19, 2024). Intervention: Patients were randomized 1:1 to receive either tiragolumab, 600 mg, plus atezolizumab, 1200 mg, plus chemotherapy (pemetrexed, 500 mg/m2, and carboplatin [area under the curve 5], or cisplatin, 75 mg/m2) or placebo plus pembrolizumab, 200 mg, plus chemotherapy via intravenous infusion on day 1 of each 21-day cycle until disease progression, loss of clinical benefit, unacceptable toxic effect, or withdrawal of consent. Main Outcomes and Measures: Primary end points were investigator-assessed progression-free survival and overall survival. The safety and tolerability of the study drugs were also evaluated. Results: Of 542 patients in the full analysis set (mean [SD] age, 63.6 [9.3] years; 353 [65.1%] male), 269 were randomized to tiragolumab plus atezolizumab plus chemotherapy and 273 to placebo plus pembrolizumab plus chemotherapy. Overall, baseline demographics were similar between treatment groups. At data cutoff (median follow-up, 11.8 months), median investigator-assessed progression-free survival was 8.3 months (95% CI, 7.1-9.6 months) with tiragolumab plus atezolizumab plus chemotherapy vs 9.9 months (95% CI, 8.7-11.9 months) with placebo plus pembrolizumab plus chemotherapy (hazard ratio, 1.27; 95% CI, 1.02-1.57; P = .99); median overall survival was 18.9 months (95% CI, 15.2-23.8 months) vs 23.1 months (95% CI, 20.7-33.0 months) in each treatment group, respectively (hazard ratio, 1.33; 95% CI, 1.02-1.73; P = .98). Grade 3 to 4 adverse events occurred in 164 of 267 patients (61.4%) in the tiragolumab plus atezolizumab plus chemotherapy group and 165 of 272 patients (60.7%) in the placebo plus pembrolizumab plus chemotherapy group, with grade 5 AEs occurring in 27 of 267 patients (10.1%) and 16 of 272 patients (5.9%) in each group, respectively. Conclusions and Relevance: In the phase 3 SKYSCRAPER-06 randomized clinical trial, the primary end points were not met and the study has been terminated.
