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

Randomized controlled trails (RCTs) where cetuximab added to first-line platinum-based chemotherapy for patients with advanced/metastatic non-small-cell lung cancer (NSCLC) have yielded conflicting results. This meta-analysis intended to evaluate the efficacy and safety of cetuximab-based therapy (CBT) in that setting. We analyzed four eligible RCTs that included 1,003 and 1,015 patients randomized to CBT and control intervention, respectively. As compared with the noncetuximab group, CBT demonstrated an 9% reduction in the risk of disease progression [hazard ratio (HR) = 0.91; (CI = 0.83-1.00); p = 0.06], a 13% reduction in the risk of death [HR = 0.87; (CI = 0.78-0.96); p = 0.005], and an approximately 50% increase in objective response rate [odds ratio (OR) = 1.48; (CI = 1.22-1.80); p < 0.0001]. CBT-related adverse events were similar across comparisons except for toxicities known to be associated with anti-EGFR therapy. CBT produced significant clinical benefit with acceptable toxicity as a first-line strategy in patients with advanced/metastatic NSCLC. Further research is needed to identify markers predictive of cetuximab benefit in that disease.
