Atezolizumab + Chemotherapy for Advanced Non-Small Cell Lung Cancer in Japanese Clinical Practice (J-TAIL-2).
Observational study in Cancer science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04501497 (Prospective Multicenter Observational Study of Atezolizumab Combination Therapy in Patients With Unresectable, Advanced and Recurrent Non-small Cell Lung Cancer or Extensive Disease 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.

Abstract
First-line atezolizumab combination therapies were approved for the treatment of metastatic non-small cell lung cancer (NSCLC) based on results from the global phase 3 trials IMpower130, IMpower132, and IMpower150. These trials reported 12-month overall survival (OS) rates of 60%-67% with atezolizumab combination therapy. J-TAIL-2 (NCT04501497), a prospective, multicenter, observational study, evaluated atezolizumab combination therapy in routine clinical practice in Japan. Patients ≥ 20 years old with NSCLC received atezolizumab plus carboplatin and nab-paclitaxel (atezo + CnP), atezolizumab plus carboplatin or cisplatin plus pemetrexed (atezo + PP), or atezolizumab plus bevacizumab plus carboplatin and paclitaxel (atezo + bev + CP) in clinical practice. The primary endpoint was the 12-month OS rate. Secondary endpoints included OS, progression-free survival, and subgroup analyses, including IMpower-unlike (did not meet the main eligibility criteria of each IMpower trial) and IMpower-like patients. In total, 814 patients were enrolled (atezo + CnP, n = 217; atezo + PP, n = 211; atezo + bev + CP, n = 386). The IMpower-unlike group included patients with Eastern Cooperative Oncology Group performance status ≥ 2, autoimmune disease, or interstitial lung disease. Twelve-month OS rates (95% confidence interval [CI]) were 62.9% (55.8-69.2), 72.1% (65.2-77.9), and 68.3% (63.2-72.9) with atezo + CnP, atezo + PP, and atezo + bev + CP, respectively. OS hazard ratios (95% CI) in the IMpower-unlike vs. -like subgroups were 1.36 (0.91-2.05), 1.08 (0.70-1.68), and 1.49 (1.09-2.06), respectively. No new safety signals were observed. Real-world efficacy and safety for each atezolizumab combination were comparable to those in the relevant IMpower trials.
