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

backgroundPatients with multiple primary lung cancers increasingly receive multiple courses of stereotactic body radiotherapy (SBRT). We aimed to clarify the efficacy and safety of such treatments. PATIENTS AND

methodsWe reviewed a prospective lung SBRT database of patients treated for stage I non-small-cell lung cancer between June 2004 and December 2015.

resultsA total of 374 patients received a single course of SBRT, 14 received synchronous SBRT, 48 received metachronous SBRT alone, and 108 received surgery and metachronous SBRT. Median follow-up was 37.0 months for survivors. Patients who received a single course had a 3-year overall survival (OS) of 54.2% (95% confidence interval [CI], 48.8-59.3), 3-year freedom from progression (FFP) of 67.3% (95% CI, 60.9-72.9), and grade 3 or higher toxicity of 3.5%. Compared to single-course patients, patients receiving metachronous SBRT alone and patients receiving surgery and metachronous SBRT had improved OS (79.7% [95% CI, 64.4-88.9%], P < .0001 and 95.4% [95% CI, 89.2-98.0%], P < .0001, respectively) and FFP (85.8% [95% CI, 70.7-93.5], P = .03 and 95.4% [95% CI, 89.2-98.0%], P < .0001, respectively). Patients receiving synchronous SBRT had similar OS (46.4% [95% CI, 19.3-69.9%], P = .75) and similar FFP (57.5% [95% CI, 25.3-80.0%], P = .17) as single-course patients. There were no significant differences in rates of grade 3 or higher toxicity or of grade 1 or higher toxicity between single-course patients and the other groups.

conclusionPatients who received either synchronous or metachronous SBRT had no significant detriment in OS or toxicity compared to single-course patients. This supports the use of SBRT in patients with multiple primary lung cancers.
