Long-term survival data of patients with limited disease small cell lung cancer: a retrospective analysis.
Article in Investigational new drugs, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled it.
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
introductionIn patients with limited disease small cell lung cancer (LD-SCLC) treated with concurrent chemoradiotherapy (CCRT), long-term survival data have not been fully evaluated. Moreover, the association between long-term prognosis and prognostic factors has not been sufficiently investigated.
methodsIn this retrospective study, we evaluated the efficacy of CCRT in 120 patients with LD-SCLC with a plan for curative CRT using concurrent accelerated hyperfractionated radiotherapy.
resultsThe patients had a median age of 65.5 years, predominantly male (73%), and had clinical stage III disease (80%). The median follow-up time for overall survival (OS) was 72.2 months, median OS was 42.5 months, and the 3-year and 5-year survival rates were 52.4% and 41.8%, respectively. The median progression-free survival (PFS) was 12.5 months, and the 3-year and 5-year PFS rates were 37.6% and 33.6%, respectively. The 5-year OS rates of patients who achieved PFS at each time point were 70.9%, 83.6%, and 91.9% at 12, 24, and 36 months, respectively. The gradual increase in the 5-year OS rate following PFS extension and initial depression of the Kaplan-Meier curve showed disease progression frequently occurred in the first 2 years after initiation of CCRT. The Cox proportional hazards model showed no significant factors correlated with long-term survival through univariate and multivariate analyses. Although the prognostic factors associated with long-term prognosis in LD-SCLC were not identified, the 5-year survival rate was 41.8%, and among patients without disease progression at 2 years, the 5-year survival rate was 83.6%.
conclusionThese data suggested that the prognosis of patients with LD-SCLC was improving.
