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

backgroundChemoradiotherapy is the standard treatment for locally advanced non-small cell lung cancer. Unlike metastatic disease, histological differences are usually not considered while planning chemoradiotherapy. This study aimed to compare clinical outcomes and relapse patterns between squamous cell carcinomas and adenocarcinomas, and investigated possible histology-specific approaches for chemoradiotherapy in locally advanced non-small cell lung cancer.

methodsWe retrospectively analyzed the outcomes and relapse patterns in patients who received definitive chemoradiotherapy for locally advanced non-small cell lung cancer in Katsura hospital between 2003 and 2012.

resultsA total of 68 and 33 patients with squamous cell carcinomas and adenocarcinomas, respectively, were enrolled. Patients with adenocarcinoma had less advanced T stages, and a larger proportion of female patients. Other factors were not different between the two groups. The median follow-up duration in all patients and survivors was 21.3 months and 91.4 months, respectively. Median survival and relapse-free survival were not significantly different between the two groups. In contrast, the failure patterns and incidences of distant failure were significantly different. Patients with squamous cell carcinomas had predominantly locoregional disease features and a shorter duration from relapse to death compared to patients with adenocarcinoma.

conclusionFailure pattern was significantly different between the two histologies. Among relapsed patients, the prognosis was poorer in those with squamous cell carcinomas than those with adenocarcinomas. Further studies, to evaluate histology-specific approaches in chemoradiotherapy, are warranted.
