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

Purpose: To investigate the outcome of definitive proton beam therapy (PBT) for second primary non-small cell lung cancer after pneumonectomy. Patients and Methods: Between January 2006 and December 2019, 4 patients with second primary lung cancer occurring in the contralateral lung after pneumonectomy were selected from our database of patients who underwent PBT. All patients were men with a median age of 69 (range, 61-79) years at the time of PBT. The median time from pneumonectomy to PBT initiation was 104.5 (range, 92-117) months. All patients had a histology of squamous cell carcinoma and were inoperable due to poor respiratory function. Results: The median survival time was 46.6 (range, 11.7-118.4) months; 3 patients died of their primary disease and one of bacterial pneumonia. The first relapses were local recurrence inside the irradiated field ( Conclusion: Definitive PBT for new lesions in the residual lung after pneumonectomy was successful without serious adverse events, although the number of cases was small.
