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

backgroundDurvalumab after concurrent chemoradiotherapy (CCRT) for locally advanced non-small cell lung cancer (LA-NSCLC) has been found to significantly improve overall survival (OS). However, the effect of durvalumab on local control remains unclear. Here, we evaluated the effect of the durvalumab on local control in comparison with the clinical result of patients treated with CCRT alone.

methodsA total of 120 LA-NSCLC patients including 76 patients with CCRT alone and 44 patients with CCRT followed by durvalumab were analyzed. Baseline patient characteristics of CCRT alone cohort and durvalumab cohort were compared with student's t test or Mann-Whitney U test for continuous variables and with chi-squared test for categorical variables. Local control (LC), progression free survival (PFS) and OS rates were estimated using the Kaplan-Meier method and compared with the log-rank test.

resultsThere were 19 patients with stage II disease and 101 patients with stage III disease. Age, sex, histopathological type, T classification, N classification, clinical stage, tumor volume and dose fractionation schedule were not significantly different between the CCRT alone and durvalumab cohorts. The one-year LC rate was significantly higher in the durvalumab cohort (86%) compared with the CCRT alone cohort (62%) (P = 0.005), whereas no significant difference was observed in either PFS (P = 0.864) or OS (P = 0.443) between the CCRT and durvalumab cohorts.

conclusionsThe one-year LC rate was significantly higher in the durvalumab cohort compared with the CCRT alone cohort. Although the follow-up period was too short to draw definitive conclusions, the study revealed that durvalumab might have a significant effect on LC. KEY POINTS: SIGNIFICANT FINDINGS OF THE STUDY: Effect of durvalumab on local control after chemoradiotherapy for locally advanced non-small cell lung cancer is unclear WHAT THIS STUDY ADDS: The one-year local control rate of chemoradiotherapy followed by durvalumab was significantly higher compared with chemoradiotherapy alone.
