Methotrexate and doxycycline interaction: a rare cause of pancytopenia.
Article in BMJ case reports, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Methotrexate (MTX) was originally formulated as one of the first antitumour drugs due to its ability to alter folate metabolism, which renders it to be an antiproliferative agent. Classically, the higher dosage is administered via parenteral route, in a cyclical fashion, to achieve antitumour effects. Patients on high doses of MTX are prone to develop rare complications of myelosuppression and pancytopenia, in a dose-dependent fashion, secondary to altered folate metabolism.
