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

Tepotinib is a key drug for cancer patients with mesenchymal-epithelial transition receptor tyrosine kinase proto-oncogene (MET) exon 14 skipping mutation. However, its bioavailability in the cerebrospinal fluid (CSF) in humans has not been fully elucidated. Moreover, information about the efficacy of tepotinib in patients with leptomeningeal metastasis is limited. Here, we present the case of a 56-year-old man who was diagnosed with lung adenocarcinoma with MET exon 14 skipping mutation. He was urgently hospitalized due to leptomeningeal metastasis. We administered tepotinib 500 mg/day as the second-line therapy and observed improvement in leptomeningeal metastasis and performance status. The tepotinib concentrations reached 1,648 ng/mL in the plasma and 30.6 ng/mL in the CSF, with a penetration rate (CSF/plasma) of 1.83%. These demonstrate tepotinib could achieve a high rate of central nervous system transition and could be effective against leptomeningeal metastasis.
