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

objectivesSurgery is the standard treatment in early-stage non-small-cell lung cancer and select cases of small-cell lung cancer, but gender differences in its use and outcome are poorly known. Gender differences in surgical resection rates and long-term survival after lung cancer surgery were therefore investigated.

methodsIn Finland, 3524 patients underwent resection for primary lung cancer during 2004-2014. Surgical rate and mortality data were retrospectively retrieved from 3 nationwide compulsory registries. Survival was studied by comparing propensity-matched cohorts. Median follow-up was 8.6 years.

resultsSurgery rate was higher in women (15.9% vs 12.3% in men, P < 0.0001). Overall survival was 85.3% 1 year, 51.4% 5 years, 33.4% 10 years and 24.2% at 14 years from surgery. In matched groups, survival after resection was better in women after 1 year (91.3% vs 83.3%), 5 years (60.2% vs 48.6%), 10 years (43.7% vs 27.9%) and 14 years (29.0% vs 21.1%) after surgery [hazard ratio (HR) 0.66; confidence interval (CI) 0.58-0.75; P < 0.0001]. Of all first-year survivors, 39.1% were alive 10 years and 28.3% 14 years after surgery. Among these matched first-year survivors, women had higher 14-year survival (36.9% vs 25.3%; HR 0.75; CI 0.65-0.87; P = 0.0002).

conclusionsSurgery is performed for lung cancer more often in women. Women have more favourable short- and long-term outcome after lung cancer surgery. Gender discrepancy in survival continues to increase beyond the first year after surgery.
