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

Background: Hypofractionated radiotherapy in locally advanced limited-stage small cell lung cancer is preferred in many Western countries but not used regularly in the United States. We examined practice patterns and overall survival with definitive hypofractionated radiotherapy and chemotherapy Methods: We included patients in the National Cancer Database with unresected primary stage II-III small cell lung cancer in 2008-2016 who underwent chemotherapy within six months of either hypofractionated radiotherapy (40-45 Gy/15 fractions) or standard radiotherapy (45 Gy/30 fractions or 60-70 Gy/30-35 fractions) in this retrospective cohort study. Patient characteristics were assessed with univariable and multivariable logistic regression. Kaplan-Meier estimator, log-rank test, and multivariable Cox regression were used to evaluate overall survival. Propensity score matching (PSM) was performed as a sensitivity analysis. Early concurrent chemotherapy consisted of radiotherapy and chemotherapy initiated within 30 days of each other. Results: Seven thousand and one hundred forty-three patients were included: 97.9% received standard radiotherapy and 2.1% hypofractionated radiotherapy. Multivariable analysis on the whole cohort yielded comparable overall survival (HR for hypofractionated radiotherapy 1.09, CI: 0.90-1.32, P=0.37). On PSM (N=292), median overall survival was similar between standard radiotherapy [22.9 months (95% CI: 18.2-30.4 months)] Conclusions: Overall survival with hypofractionated radiotherapy appears similar to standard radiotherapy in locally advanced limited-stage small cell lung cancer. Chemotherapy timing may modify the effect of fractionation on overall survival, though larger numbers must confirm. Hypofractionated radiotherapy may be considered in those unable to receive early concurrent chemotherapy.
