Reproducibility of a time-resolved NIRS, multidistance diffuse correlation spectroscopy system: towards noninvasive longitudinal neuromonitoring.
Article in Neurophotonics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Significance: Longitudinal monitoring of cerebral blood flow (CBF), oxygenation ( Aim: Reproducibility and reliability of an in-house time-resolved near-infrared spectroscopy (trNIRS)/multidistance diffuse correlation spectroscopy (mdDCS) system were assessed to determine the feasibility of daily monitoring. In addition, carotid compression was performed to demonstrate longitudinal monitoring. Approach: Time-resolved NIRS/mdDCS measurements were acquired daily on volunteers across one week. Reproducibility was quantified by the coefficient of variation (CV) and reliability by the intraclass correlation coefficient (ICC) at three levels: within-acquisition, between-acquisition, and between-day. A subset of participants returned on day 21+, and carotid compression was performed to reduce CBF. Signal changes during compression were compared to baseline measurements from that day and previous days. Results: All optical measurements showed good-to-excellent within-acquisition, between-acquisition, and between-day reproducibility ( Conclusions: This study demonstrates the feasibility of daily monitoring using a hybrid trNIRS/mdDCS system.
