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

backgroundAlthough immune checkpoint inhibitor-related endocrine adverse reactions are common in clinical practice, fulminant type 1 diabetes induced by tislelizumab remains rare. CASE PRESENTATION: A 68-year-old Asian female patient was diagnosed with stage IV BRAF V600E-mutant lung adenocarcinoma via pleural biopsy in August 2020 and initially treated with dabrafenib and trametinib. In March 2023, she started treatment with tislelizumab owing to a new metastasis in the left lower lung. On 20 May 2024, the patient was admitted to the hospital with a 3-day history of the sudden onset of dry mouth, polydipsia, and polyuria, accompanied by mild nausea and vomiting. Laboratory examination results showed hyperglycemia, ketosis, and mild metabolic acidosis, but HbA1c was mildly elevated at 7%. The C-peptide release test indicated severe insulin deficiency. She was diagnosed with fulminant type 1 diabetes, treated with intravenous insulin and fluid resuscitation, and discharged. A total of 6 months after discontinuing tislelizumab, her pancreatic function had not recovered.

conclusionTislelizumab can induce fulminant type 1 diabetes via immune-mediated mechanisms. Proactive monitoring of fasting glucose, HbA1c, and islet function is essential for patients with cancer receiving tislelizumab therapy.
