Adjuvant Chemotherapy After Neoadjuvant Therapy and Surgery for Non-Small Cell Lung Cancer.
Article in Annals of thoracic surgery short reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: There is a dearth of data on outcomes of postoperative chemotherapy after neoadjuvant therapy followed by surgery in patients with locally advanced non-small cell lung cancer (NSCLC). The objective of this study was to compare survival outcomes in patients who did and did not receive adjuvant chemotherapy. Methods: A retrospective chart review was performed using our multicenter database to identify patients who received neoadjuvant therapy followed by surgery for clinical T3 N0 or N1-N2 resectable NSCLC between 2009 and 2016. Survival outcomes were analyzed with the Kaplan-Meier method and a Cox proportional hazards model. Propensity score matching (PSM) was used to control for selection bias in evaluation of overall survival (OS) and recurrence-free survival (RFS) by matching age, sex, smoking history, Charlson Comorbidity Index, histologic type, and pathologic nodal status and stage. Results: The participants were 156 patients with a median age of 65 years. The median RFS of the whole cohort was 66.3 months; OS was not reached. Before PSM, patients receiving adjuvant chemotherapy had significantly shorter RFS (hazard ratio [HR], 1.79; 95% CI, 1.13-2.82) and showed a trend for shorter OS (HR, 1.37; 95% CI, 0.78-2.39). After PSM, 50 patients were used for comparison in each group, and those receiving adjuvant chemotherapy did not have a more favorable RFS (HR, 1.33; 95% CI, 0.75-2.34) or OS (HR, 1.25; 95% CI, 0.62-2.51). Conclusions: Adjuvant chemotherapy was not associated with favorable survival outcomes in patients treated with surgery after neoadjuvant therapy for locally advanced NSCLC.
