Clinical utility of CSF Aβ38 in Japanese research and clinical cohorts.
Article in Alzheimer's & dementia (Amsterdam, Netherlands). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
introductionPrevious studies have reported that cerebrospinal fluid (CSF) amyloid beta (Aβ42/Aβ38) performs comparably to Aβ42/Aβ40 in predicting amyloid positron emission tomography (PET) positivity in White cohorts. However, this finding has not been validated in diverse populations. Moreover, the utility of CSF Aβ38 in diagnosing various neurological diseases has not been fully understood.
methodsWe analyzed CSF Aβ38, Aβ40, Aβ42, phosphorylated tau181, and neurofilament light chain in Japanese research and clinical cohorts with Alzheimer's clinical syndrome (ACS) or non-ACS.
resultsCSF Aβ42/Aβ38 predicted amyloid PET positivity comparably to Aβ42/Aβ40. The levels of CSF Aβ38 were significantly lower in patients with progressive supranuclear palsy (PSP) and idiopathic normal pressure hydrocephalus (iNPH) than in those with other diseases. DISCUSSION: We validated the high diagnostic performance of CSF Aβ42/Aβ38 in Japanese patients with AD. CSF Aβ38 reduction may be a characteristic feature of PSP and iNPH. Highlights: The diagnostic value of cerebrospinal fluid (CSF) amyloid beta (Aβ)38 was examined in Japanese research and clinical cohorts.CSF Aβ42/Aβ38 and Aβ42/Aβ40 showed comparable performance to detect brain Aβ deposition.CSF Aβ42/Aβ38 and Aβ42/Aβ40 discordant group showed a characteristic profile.CSF Aβ38 and Aβ40 were prominently decreased in progressive supranuclear palsy and idiopathic normal pressure hydrocephalus.
