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

introductionBalamuthia mandrillaris amoebic encephalitis is a rare granulomatous amoebic encephalitis caused by infection with Balamuthia mandrillaris with a fatality rate over 90%. This study characterizes the imaging manifestations of Balamuthia mandrillaris amoebic encephalitis, yields critical new insights into the intracranial dissemination mechanisms of Balamuthia mandrillaris. CASE PRESENTATION: We present two cases of Balamuthia mandrillaris amoebic encephalitis confirmed through Next-generation sequencing of cerebrospinal fluid and brain biopsy in our hospital, with different imaging manifestations and prognosis (One death). Meanwhile, we reviewed 16 surviving cases of Balamuthia mandrillaris amoebic encephalitis reported in literatures up to now.

conclusionBased on 17 surviving patients imaging findings with clinical data and one death case we reported, we proposed that the key imaging features related to the prognosis of Balamuthia mandrillaris amebic encephalitis are hemorrhage within the lesion and centripetal spread through cortical and subcortical brain parenchyma into cerebrospinal fluid circulation along the meninges and ependyma. Starting ventriculoperitoneal shunt surgery as early as possible before the ventricular system is invaded may provide the patient with a chance of survival.
