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

Treatment of advanced stage lung cancer is changing rapidly. With the new found knowledge on molecular targets such as the epidermal growth factor receptor (EGFR), effective therapy is now available in a selected population with the target mutation. Single-agent epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) is a standard first-line therapy for patients with activating-EGFR mutation such as base-pair deletion in exon 19 or point mutation at exon 21. At the same time, this class of drugs may be combined with chemotherapy. Studies on the concurrent combination of chemotherapy and EGFR-TKI confirmed a lack of efficacy. A phase II study on sequential intercalated combination has demonstrated an improvement in progression-free survival (PFS), but this needs to be validated by the ongoing phase III study. The third approach is to combine EGFR-TKI as maintenance therapy after tumour response or stable disease to cytotoxic chemotherapy. Two phase III studies have shown improvement in PFS, but the use of biomarkers for the selection of maintenance therapy remains debatable. Cetuximab is a monoclonal antibody against EGFR and its combination with chemotherapy was shown to improve overall survival in an unselected population. A new biomarker using the H-score will help to select patients for this combination.
