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

objectiveTo evaluate the efficacy and safety of MK-801 and its effect on lesion volume in rat models of acute brain injury. DATA SOURCES: Key terms were "stroke", "brain diseases", "brain injuries", "brain hemorrhage, traumatic", "acute brain injury", "dizocilpine maleate", "dizocilpine", "MK-801", "MK801", "rat", "rats", "rattus" and "murine". PubMed, Cochrane library, EMBASE, the China National Knowledge Infrastructure, WanFang database, the VIP Journal Integration Platform (VJIP) and SinoMed databases were searched from their inception dates to March 2018. DATA SELECTION: Studies were selected if they reported the effects of MK-801 in experimental acute brain injury. Two investigators independently conducted literature screening, data extraction, and methodological quality assessments. OUTCOME MEASURES: The primary outcomes included lesion volume and brain edema. The secondary outcomes included behavioral assessments with the Bederson neurological grading system and the water maze test 24 hours after brain injury.

resultsA total of 52 studies with 2530 samples were included in the systematic review. Seventeen of these studies had a high methodological quality. Overall, the lesion volume (34 studies, n = 966, MD = -58.31, 95% CI: -66.55 to -50.07; P < 0.00001) and degree of cerebral edema (5 studies, n = 75, MD = -1.21, 95% CI: -1.50 to -0.91; P < 0.00001) were significantly decreased in the MK-801 group compared with the control group. MK-801 improved spatial cognition assessed with the water maze test (2 studies, n = 60, MD = -10.88, 95% CI: -20.75 to -1.00; P = 0.03) and neurological function 24 hours after brain injury (11 studies, n = 335, MD = -1.04, 95% CI: -1.47 to -0.60; P < 0.00001). Subgroup analysis suggested an association of reduction in lesion volume with various injury models (34 studies, n = 966, MD = -58.31, 95% CI: -66.55 to -50.07; P = 0.004). Further network analysis showed that 0-1 mg/kg MK-801 may be the optimal dose for treatment in the middle cerebral artery occlusion animal model.

conclusionMK-801 effectively reduces brain lesion volume and the degree of cerebral edema in rat models of experimental acute brain injury, providing a good neuroprotective effect. Additionally, MK-801 has a good safety profile, and its mechanism of action is well known. Thus, MK-801 may be suitable for future clinical trials and applications.
