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

Human umbilical cord mesenchymal stem cells (hUC-MSCs) support revascularization, inhibition of inflammation, regulation of apoptosis, and promotion of the release of beneficial factors. Thus, they are regarded as a promising candidate for the treatment of intractable spinal cord injury (SCI). Clinical studies on patients with early chronic SCI (from 2 months to 1 year post-injury), which is clinically common, are rare; therefore, we will conduct a prospective, multicenter, randomized, placebo-controlled, single-blinded clinical trial at the Third Affiliated Hospital of Sun Yat-sen University, West China Hospital of Sichuan University, and Shanghai East Hospital, Tongji University School of Medicine, China. The trial plans to recruit 66 early chronic SCI patients. Eligible patients will undergo randomization at a 2:1 ratio to two arms: the observation group and the control group. Subjects in the observation group will receive four intrathecal transplantations of stem cells, with a dosage of 1 × 10
