Identifying the superior and inferior gluteal arteries during a sacrectomy via a posterior approach.
Article in Journal of spine surgery (Hong Kong), 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundIdentifying the gluteal vessels during a posterior sacrectomy can be challenging. This study defines anatomical landmarks that can be used to approximate the location of the superior and inferior gluteal arteries (SGA and IGA) during a posterior sacrectomy.
methodsCadaveric dissection of six fresh adult pelvises to determine the location of the SGA and IGA in relation to the posterior-inferior aspect of the sacroiliac joint (PISIJ), lateral sacral margin and sacrococcygeal joint (SCJ).
resultsThe anatomical landmarks are easily palpable. The position of the SGA to the PISIJ is relatively constant as it is tethered by a posterior branch of the artery, which runs inferior to the PISIJ. The IGA position is also relatively constant below the mid-point of the PISIJ and SCJ. The vessels are separated from the sacrospinous/sacrotuberous ligament complex (SSTL) in the perisacral region and as a result an anatomical plane exists anterior to the SSTL, which affords protection of the vessels during SSTL transection. The distance between the vessels and the SSTL increases the more medial the dissection.
conclusionsThe described anatomical landmarks can be used to predict the location of the SGA and IGA during posterior sacrectomy. An anatomical plane exists anterior to the SSTL, which provides protection to the vessels during SSTL transection. Furthermore, the distance between the vessels and the SSTL increases the more medial the dissection, thus, resection of the SSTL as close to the lateral sacral margin as the pathology permits, is advocated.
