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

purpose- As a potential cause of compression resulting in neuropathic pain or using to secure coxal bone procedure, the proximity of sciatic nerve against coxal bone inside the infra-piriform foramen was unclear.

methods- This systematic review focused on the relationship between pelvic bone and sciatic nerve based on PRISMA methodology.

results- A total of 26 studies involving 4,813 lower limbs were included in the meta-analysis. The variations of the sciatic nerve in relation to the piriform muscle were described in 14.5% of cases. The variation involving division of the sciatic nerve in the pelvis, with the common fibular nerve passing over the piriformis muscle and the tibial nerve passing through it, was never observed. However, a variation in which the sciatic nerve divided in the pelvis, with its two terminal branches (the common fibular nerve and the tibial nerve) passing separately under the piriformis muscle, was described in 0.81% of cases.

conclusion- There was no data available to analyse the distance between the sciatic nerve and the coxal bone as it exited the pelvis.
