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

Extramedullary hematopoiesis (EMH) is a compensatory process that supplements defective hematopoiesis and is frequently observed in myeloproliferative neoplasms (MPNs). Liver, spleen, and lymph nodes are the most common sites of EMH, whereas its occurrence in the intracranial space is extremely rare. We experienced a case of EMH which developed in cranial dura mater after irradiation against massive splenomegaly. As general condition of the patient did not allow us pathological examination, the diagnosis was confirmed by postmortem autopsy.
