Rebuilding the atrophied brain: 6-month nasal esketamine therapy expands key frontal and hippocampal regions and reduces serum neurofilament levels in patients with major depressive disorder. A proof-of-concept study of the depTesk (DEPression treatment with ESKetamine) study.

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
objectivesThis proof-of-concept study aimed to assess the impact of intranasal esketamine (ESK-IN) in brain volume and neurofilament light chain (sNfL) over 6-months in patients with treatment resistant depression (TDR).
methodsSeven TRD patients received ESK-IN while continuing oral antidepressants. Clinical evaluations were conducted at baseline, 1, 3, and 6 months, with MRI scans and blood samples taken at baseline and 6 months. Brain volume was assessed using VolBrain2 and DSI studio.
resultsCompared to controls, TRD patients initially showed lower volumes (mm
conclusionsESK-IN may promote structural changes in regions associated with mood regulation and neuroplasticity, while also reducing neuronal damage in TRD patients.
