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

purposeWe sought to investigate visual cortex neural activity and functional connectivity (FC) alterations in cervical spondylotic myelopathy (CSM) patients using resting-state fMRI (rs-fMRI) and to explore the relationships of these alterations with visual disorder.

methodsTwenty-seven CSM patients and 11 healthy controls were recruited as the study and control groups. The amplitude of low-frequency fluctuations (ALFF) and regional homogeneity (ReHo) values were calculated to represent neural activity, seed-based correlation analysis (SCA) was performed to analyze the FC of visual cortex, and the outcomes were compared between groups. The preoperative best-corrected visual acuity (pre-BCVA) and postoperative BCVA (post-BCVA) of study groups were measured. Correlation analyses of the ALFF/ReHo values with the preoperative and postoperative BCVAs were performed. Correlations of the bilateral BCVAs with the ipsilateral and contralateral visual cortex neural activities were performed.

resultsThe ALFF/ReHo values were decreased in the occipital lobe and increased in the cerebellar posterior lobe in the study group (P < 0.05). Increased FC was demonstrated between Brodmann's area 17 and posterior cingulate lobe (P < 0.05). Postoperatively, the BCVAs were ameliorated in 22 oculi dexter (ODs) and 20 oculi sinister (OSs) in the study group. Positive correlations between neural activity in the visual cortex and the preoperative and postoperative BCVAs were detected in the study group. The bilateral BCVAs were positively correlated with either the ipsilateral or contralateral visual cortex neural activity.

conclusionBoth ALFF/ReHo value changes and positive correlations of these changes with BCVA were demonstrated in CSM. The FC between the visual cortex and posterior cingulate lobe was also increased in CSM.
