T-cell prolymphocytic leukaemia associated with immune checkpoint inhibitor (pembrolizumab).
Article in BMJ case reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
We describe the case of a man in his 60s with squamous cell carcinoma of the lung with brain metastasis treated with pembrolizumab who subsequently developed T-cell prolymphocytic leukaemia. He was transferred to our hospital with worsening dyspnoea, suspected hyperviscosity syndrome and tumour lysis syndrome. He was intubated and admitted to our critical care unit. Emergent leucapheresis was started due to worsening renal function in the setting of tumour lysis and hyperviscosity syndromes. He continued to deteriorate and required continuous renal replacement therapy. Unfortunately, he eventually died from haemodynamic decompensation. There are only a few anecdotal cases pointing at a possible association between the use of immune checkpoint inhibitors and the progression or exacerbation of secondary haematological malignancies. The poor prognosis of these haematological malignancies warrants further investigation to determine if checkpoint inhibitors increase the risk of developing or propagating these potentially fatal diseases.
