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
Fever of unknown origin (FUO) is a common diagnostic dilemma faced by internists on a fairly regular basis. A wide variety of infectious, autoimmune, and neoplastic conditions can present with FUO. Splenic B-cell lymphoma/leukemia with prominent nucleolus (SBLPN), formerly known as hairy cell leukemia-variant, is a hematologic malignancy that often presents with massive splenomegaly and pancytopenia. Initial presentation of SBLPN as FUO is exceedingly rare. Here, we present the case of an elderly gentleman in his 80s who presented with fever, night sweats, weight loss, and recurrent falls. He was subsequently diagnosed with SBLPN after 6 weeks of extensive diagnostic evaluation. The practicing internist needs to be aware of this initial presentation of SBLPN as FUO and have a low suspicion to proceed with a bone marrow aspiration and biopsy to clench the diagnosis in the right clinical context.
