First-Line Tislelizumab Plus Chemotherapy for Advanced or Metastatic Squamous Non-Small Cell Lung Cancer: 4-Year Long-Term Follow-Up from RATIONALE-307.
Article in Oncology and therapy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the 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.

Abstract
introductionSquamous nonsmall cell lung cancer (sq-NSCLC) is challenging to treat, with shorter survival when compared with other NSCLC subtypes. Tislelizumab has demonstrated efficacy when combined with chemotherapy for sq-NSCLC. We report 4-year follow-up results from the phase 3 randomized RATIONALE-307 trial evaluating tislelizumab plus chemotherapy as first-line treatment for advanced or metastatic sq-NSCLC.
methodsPatients with treatment-naive advanced or metastatic sq-NSCLC were randomized to receive tislelizumab plus paclitaxel/carboplatin (arm A), tislelizumab plus nab-paclitaxel/carboplatin (arm B), or paclitaxel/carboplatin alone (arm C) until disease progression/intolerable toxicity. Crossover was permitted from arm C to tislelizumab monotherapy. The primary end point was progression-free survival (PFS) per independent review. Key secondary end points included overall survival (OS) and safety.
resultsAt median OS follow-up of 44.8 months, tislelizumab plus chemotherapy demonstrated durable survival benefit. Median PFS was 7.7 months (95% confidence interval [CI] 6.7-9.9) in arm A, 9.5 months (95% CI 7.4-10.1) in arm B, and 5.5 months (95% CI 4.2-5.6) in arm C. Median OS was 26.1 months (95% CI 19.0-33.8) in arm A, 23.3 months (95% CI 18.8-26.4) in arm B, and 19.4 months (95% CI 16.0-23.4) in arm C. The 4-year OS rates were 32.2%, 26.0%, and 19.2% for arms A, B, and C, respectively. Crossover occurred in 58.7% of patients from arm C. OS and PFS benefits were observed across most subgroups. Grade ≥ 3 treatment-emergent adverse events occurred in 89.2%, 89.0%, and 84.6% of patients in arms A, B, and C, respectively. No new safety signals emerged.
conclusionsAt 4-year follow-up, patients with advanced sq-NSCLC who received tislelizumab plus chemotherapy experienced long-term OS and PFS benefits versus chemotherapy alone, despite high crossover rates. The combination was well-tolerated with no new safety concerns. This regimen may be a promising first-line treatment option for patients with advanced or metastatic sq-NSCLC.
