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

Excision repair cross-complementation group 1 (ERCC1) protein has been associated with cisplatin resistance. The objective of this study was to investigate the correlation between ERCC1 protein levels and the therapeutic effect of individualized therapy in advanced non-small cell lung cancer (NSCLC). A total of 190 advanced NSCLC patients were included in this study. Patients were randomized into either the individualized therapy group or the standard therapy group at a ratio of 2:1. Patients in the standard therapy group were treated with either gemcitabine plus cisplatin or vinorelbine plus cisplatin. The expression of ERCC1 protein in lung cancer tissues of patients from the individualized therapy group was detected with immunohistochemistry. Patients with low ERCC1 levels received either gemcitabine plus cisplatin or vinorelbine plus cisplatin, and patients with high levels received gemcitabine plus vinorelbine. The main outcome assessments were response rate (RR), overall survival (OS) and time to progression (TTP). Follow-up data were recorded until September 30, 2010. RR, 1-year survival rate and TTP were not statistically significant. The median survival time was 10.10 months in the standard therapy group (95% CI 8.48-11.92) and 13.59 months in the individualized therapy group (95% CI 11.86-14.74). The difference in median survival time was significantly different between these groups (P=0.036). The median survival time was longer in the individualized group compared to the standard therapy group. ERCC1 protein expression in advanced NSCLC patients, however, was not significantly correlated with RR, OS and TTP in the individualized therapy group. Therefore, this study suggests that ERCC1 protein levels should be assessed in combination with additional biomarkers to determine an optimal index for individualized therapy in advanced NSCLC patients.
