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

Severe traumatic brain injury (sTBI) survivors experience permanent functional disabilities due to significant volume loss and the brain's poor capacity to regenerate. Chondroitin sulfate glycosaminoglycans (CS-GAGs) are key regulators of growth factor signaling and neural stem cell homeostasis in the brain. In this protocol, we describe how to perform recordings to quantify the neuroprotective and regenerative effect of implanted engineered CS-GAG hydrogel (eCS) on brain tissue. This experiment was performed in rats under three conditions: healthy without injury (Sham), controlled cortical impact (CCI) injury on the rostral forelimb area (RFA), and CCI-RFA with eCS implants. This protocol describes the procedure used to perform the craniotomy, the positioning of the cortical recording electrode, the positioning of the stimulation electrode (contralateral paw), and the recording procedure. In addition, a description of the exact electrical setup is provided. This protocol details the recordings in the brain of injured animals while preserving most of the uninjured tissue intact, with additional considerations for intralesional and laminar recordings of multi-unit response.
