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

objectiveOverall survival (OS) for advanced stage (IIIA-IV) non-small cell lung cancer (NSCLC) is highly variable, and retrospective data show a survival advantage for patients receiving therapeutic intent pulmonary resection. We hypothesized that this variability in OS can be modeled separately by stage to allow a personalized estimate of OS.

methodsIn a cohort of patients with advanced-stage NSCLC from the National Cancer Database, we assessed the accuracy of Surgical Selection Score (SSS) to predict OS using Cox proportional hazards models and determined by stage the effect of surgery on survival among people with similarly high levels of SSS.

resultsIn total, 300,572 patients were identified; 18,701 (6%) had surgery. The SSS was a strong predictor of OS (C-index, 0.89; 95% confidence interval [CI], 0.89-0.90). We observed significantly greater OS (P < .001) among patients who had surgery. The hazard of death was at least 2 times greater for patients in the upper quartile of SSS who did not receive surgery compared with surgical patients even when adjusting for the SSS (stage IIIA: hazard ratio [HR], 2.1; 95% CI, 2.0-2.2, stage IIIB: HR, 2.3; 95% CI, 2.2-2.5, stage IV: HR, 2.3; 95% CI, 2.2-2.4).

conclusionsThe SSS is highly predictive of individual OS and can be used as a risk assessment tool. These findings are important for a more robust evaluation of the likely benefits of surgical resection for these patients. After further prospective validation, the SSS can be used during treatment decision-making for patients with advanced-stage NSCLC.
