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

purposeTropomyosin receptor kinase (TRK) inhibitors have emerged as a promising class of targeted therapies for patients with tumors containing neurotrophic tyrosine receptor kinase (NTRK) gene fusions. While not noted in early clinical studies, about one-third of patients can experience diffuse arthralgias, myalgias, and allodynia in the contexts of missed, delayed, or discontinued therapy, resembling withdrawal-like symptoms. Here we report a case of a patient who had daily withdrawal-like symptoms which resolved after starting semaglutide. CASE PRESENTATION: A 35-year old male with metastatic/recurrent ETV6-NTRK3 fusion parotid gland cancer was enrolled on a clinical study investigating the efficacy of larotrectinib. He had a rapid complete response to therapy, and has continued on therapy for more than seven years. Early after starting therapy he experienced twice a day diffuse myalgias, arthralgias, and light sensitivity starting 30 to 45 min before his next dose was due. This continued until he was started on semaglutide, a GLP-1 receptor agonist, after which his symptoms completely resolved.

conclusionGLP-1 receptor agonists may have a role in improving side effects from larotrectinib. Possible mechanisms for this effect are discussed, with further research needed.
