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
backgroundExtensive-stage small cell lung cancer (ES-SCLC) is a malignant tumor with remarkable proliferative and invasive ability, which has very poor clinical prognosis due to lack of effective treatments. This study aims to evaluate the efficacy and synergistic effects of radiotherapy (RT) combined with immunotherapy (IT) and chemotherapy (CT) in patients with ES-SCLC.
methodsA retrospective analysis was performed on 145 ES-SCLC patients treated with first-line CT. Kaplan-Meier analysis and Log-rank tests were used to evaluate survival outcomes, while propensity score matching (PSM) was applied to reduce confounding factors.
resultsThe median overall survival (mOS) and median progression-free survival (mPFS) for the entire cohort were 15.7 and 6.9 mon, respectively. The IT+CT group had a significantly longer mOS compared to the CT group (17.2 vs 13.5 mon, P=0.047). Similarly, the RT+CT group demonstrated superior mOS (18.5 vs 12.3 mon, P<0.001) and mPFS (7.1 vs 6.2 mon, P=0.006) compared to the CT group. Multivariate analysis identified RT, IT, and Eastern Cooperative Oncology Group performance status (ECOG PS) as independent prognostic factors for mOS (P<0.05), while gender and ECOG PS were independent predictors for mPFS (P<0.05). Following PSM, the RT+CT group continued to exhibit significant advantages in mOS (18.0 vs 12.1 mon, P<0.001) and mPFS (7.1 vs 5.5 mon, P=0.037) compared to the CT group. Notably, the RT+IT+CT group achieved a markedly longer mOS than the IT+CT group (28.5 vs 15.8 mon, P=0.017). Grade 3-4 adverse events occurred in 27.6% of patients, with no grade 5 adverse events reported.
conclusionsThe combination of RT, IT, and CT significantly enhances the prognosis of ES-SCLC patients. RT plays a key role in their synergistic effects and demonstrates good safety, warranting further research and clinical application.
