1 · What the graph read from 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.

2 · The registry

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

aimsThis study aimed at developing a scoring system (EAST score) to predict recurrence after chemoradiotherapy in limited-stage small-cell lung cancer (LS-SCLC). PATIENTS &

methodsTreatment-naïve LS-SCLC patients receiving concurrent chemoradiotherapy (CCRT) (

resultsEAST score incorporated N3 disease and serum biomarkers (lactate dehydrogenase, pro-gastrin-releasing peptide, and cytokeratin-19 fragment). In the CCRT population, progression-free survival (PFS) was significantly shorter in the high-risk group (EAST score ≥ 2) than the low-risk group (EAST score ≤ 1) (median, 9.4 months vs. 20.6 months; HR [95% confidence interval (CI)], 2.09 [1.50-2.91]). As for the model performance, the 1- and 2-year area under the curve values for PFS were 0.68 and 0.65, respectively. Overall survival was also shorter in the high-risk group (HR [95% CI], 1.49 [1.02-2.16]). Similar trends were observed in the sequential chemoradiotherapy population (HR for PFS [95% CI], 2.43 [1.07-5.53]).

conclusionsEAST score effectively predicts recurrence risk in LS-SCLC, demonstrating the necessity for developing new treatment strategies for high-risk patients.
