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

objectiveTo assess the efficacy and safety of anti-epidermal growth factor receptor (EGFR) therapy versus non-anti-EGFR therapy for advanced head and neck squamous cell carcinoma (HNSCC).

methodsThe Cochrane Central Register of Controlled Trials, Medline, and Embase databases were searched for relevant reports. Quantitative analysis was carried out to evaluate the overall response rate (ORR), overall survival (OS), progression free survival (PFS), and grade 3-4 adverse effects.

resultsTen reports involving 2,396 patients were included. Primary meta-analysis indicated that anti-EGFR therapy could improve ORR [relative risk (RR) 1.36, 95% confidence interval (CI) 1.12-1.67] and PFS [hazard ratio (HR) 0.63, 95% CI 0.55-0.71), but failed to improve OS (HR 0.88, 95% CI 0.74-1.03). In subgroup analyses, we found that monoclonal antibodies (Mabs) could improve ORR, OS, and PFS for both locoregionally advanced (LA) (ORR: 1.21, 1.08-1.37; OS: 0.72, 0.59-0.89; PFS: 0.66, 0.53-0.83) and recurrent/metastatic (RM) HNSCC (ORR: 1.88, 1.40-2.54; OS: 0.79, 0.67-0.94; PFS: 0.61, 0.52-0.71), while tyrosine kinase inhibitors (TKIs) did not improve any of these in patients with either LA (ORR: 1.09, 0.91-1.32; OS: 0.7, 0.31-1.63; PFS: 0.71, 0.34-1.52) or RM (ORR: 1.65, 0.84-3.24; OS: 1.13, 0.97-1.31; PFS: not available) HNSCC. Analysis of adverse effects demonstrated that rash (RR 14.34, 95% CI 5.02-41.02), diarrhea (2.36, 1.15-4.87), and anorexia (2.49, 1.11-5.56) were significantly associated with anti-EGFR therapy.

conclusionsAnti-EGFR Mabs are effective for both LA and RM HNSCC. In contrast, TKIs were unsuitable for treatment of advanced HNSCC. During anti-EGFR therapy, rash and some gastrointestinal reactions, such as diarrhea and anorexia, should be carefully monitored.
