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

backgroundSarcopenia has recently emerged as a new condition with increasing importance in lung cancer patients. The aim of this study was to investigate the influence of sarcopenia on tolerance and efficacy of afatinib.

methodsWe retrospectively evaluated 35 patients with epidermal growth factor receptor (EGFR) mutant advanced non-small cell lung cancer (NSCLC) treated with first-line afatinib. Skeletal muscle area (SMA) was measured at the third lumbar vertebra using routine conducted computed tomography (CT) images for evaluation of disease burden. Sarcopenia was defined as skeletal muscle index (SMI = SMA/height

resultsThe median age at diagnosis was 65 years (range,39-84 years). A total of 24 (68.6%) patients were diagnosed with sarcopenia. The most frequent adverse events (AEs) related to afatinib were diarrhea (94.3%) followed by rash (77.1%) and paronychia (60%). Overall, 19 (54.3%) patients had dose reduction. Sarcopenic patients had a significantly higher rate of grade ≥ 2 diarrhea (75.0 vs. 27.3%, p = 0.011) and toxicity-related dose reduction (75.0 vs. 9.1%, p = 0.001). Multivariate analysis also showed that sarcopenia (odds ratio [OR] 51.7, 95% confidence interval [CI]: 2.4-1081.3, p = 0.01) was an independent risk factor for dose reduction of afatinib. The median progression-free survival (PFS) for afatinib was 12.0 months (95% CI: 10.6-13.4). Both dose reduction and sarcopenia did not affect therapeutic efficacy.

conclusionsToxicity-related dose reduction is common with initiation of afatinib 40 mg/day. Sarcopenic patients might begin treatment with a low dose of afatinib according to tolerance.
