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
Background: For patients with resectable epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC), the optimal neoadjuvant regimen remains undefined. In this multicenter retrospective cohort study, we explored the efficacy and safety of immunochemotherapy, tyrosine kinase inhibitors (TKIs), and chemotherapy as perioperative treatments for patients with resectable NSCLC harboring Methods: Patients with untreated stage IIA-IIIB NSCLC and Results: Between January 13, 2020, and September 1, 2023, of 64 patients screened, 41 patients from seven centers were included in the final efficacy analysis. The ORR of the immunochemotherapy group, the TKI group, and the chemotherapy group was 63.0% [95% confidence interval (CI): 42.4-80.6%], 41.7% (95% CI: 15.2-72.3%), and 100% (95% CI: 15.8-100%), respectively. A total of 40 patients (97.5%) underwent definitive surgery, and 55.9% of the patients achieved lymph node downgrade. Among all 40 patients receiving definitive surgery, 10 patients achieved MPR, and the MPR rate was 25.0% (95% CI: 12.7-41.2%). The pCR rate was 10.0% (95% CI: 2.8-23.7%). For the immunochemotherapy group, the MPR rate was 30.8%, and for the TKI group, the MPR rate was 8.3% (P=0.08). The pCR rates of the immunochemotherapy group and the TKI group were 15.4% and 0%, respectively (P=0.18). With a follow-up of 24.0 months, the median EFS was not reached, and the 12-month and 24-month EFS rates were 94.2% and 75.8%, respectively. Treatment-related adverse events were manageable. Conclusions: The combination of immunotherapy and chemotherapy as neoadjuvant treatment demonstrated a promising pathological response among patients with
