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 study the distribution of sympathetic nerves of the ligamentum flavum (LF), confirm its existence by histological observation and nuclear magnetic resonance spectroscopy, and analyze the relationship between sympathetic nerve fibers and the biomechanical structure of the LF.

methodsRandomly controlled scientific research selected 15 cases of posterior surgery in the affiliated hospital of Qingdao University from January 2013 to December 2019. The average age was 67.5 ± 14.5 years old, eight males and seven females. The LF specimens (completely separated fresh tissue) of different segments (C

resultsThere were type C sympathetic nerve fibers in the LF, which were divided into linear shape (α) and wave shape (β). Experimental group (χ

conclusionsThere are many sympathetic nerve fibers distributed on LF, and their distribution may be correlated with histological and mechanical characteristics of LF. It may also be the anatomical basis of cervical vertigo.
