Topographical study of the trapezius muscle, greater occipital nerve, and occipital artery for facilitating blockade of the greater occipital nerve.
Article in PloS one, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
The aim of this study was to clarify the topographical relationships between the greater occipital nerve and the trapezius muscle and between the greater occipital nerve and the occipital artery in the occiput in order to increase the success rate of greater occipital nerve blockade. Fifty-six halved heads of 28 cadavers were used in this study. The piercing points and the courses of the greater occipital nerve and occipital artery were analyzed by dividing a line connecting between the external occipital protuberance and mastoid process into three equal parts. A circle with a radius of 2 cm drawn at the medial trisection point of this line was divided into four equal sectors. The greater occipital nerve simply passed the lateral border of the trapezius muscle and then pierced the fascia connecting the cranial attachment of the trapezius muscle with the sternocleidomastoid muscle in 62.5% of the specimens, whereas it pierced the muscle itself in the other 37.5%. The greater occipital nerve and occipital artery pierced the fascia within the 2-cm-radius circle in 85.7% and 98.2% of the specimens, respectively. The piercing points of the greater occipital nerve and occipital artery were observed most frequently in the inferomedial (42.9%) and inferolateral (37.5%) sectors of the circle, respectively. The greater occipital nerve and occipital artery pierced the same sector of the circle and accompanied each other in 51.8% of the specimens. These results are expected to improve the understanding of the topographical relationships between the greater occipital nerve and trapezius muscle and between the greater occipital nerve and occipital artery in the occiput, and thus provide helpful information for the management of occipital neuralgia.
