Hypercalcaemia, renal failure, anaemia and osteolytic lesions (CRAB) in chronic lymphocytic leukaemia mimicking multiple myeloma.
Article in BMJ case reports, 2021. 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
Classical CRAB features (hypercalcaemia, renal failure, anaemia, osteolytic lesions) have been traditionally defined in patients with plasma cell dyscrasia. But these can be rare and uncommon presentations of other chronic lymphoproliferative disorders (CLPD). The pathophysiological basis of CRAB features in other CLPD need to be explored further for better outcomes and therapeutic interventions. These can present a diagnostic dilemma and requires extensive workup to rule out coexisting malignancy and myeloma. Here, we report an unusual case of B CLPD in a middle-aged male who presented with classical CRAB features along with a brief literature review. After detailed investigations, he was diagnosed as chronic lymphocytic leukaemia, without any second malignancy and responded well to ibrutinib-based therapy.
