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

introductionAlthough the sphenopalatine ganglion (SPG) has been considered a site of therapeutic potential for cluster headache (CH), the optimal technique of SPG is still to be determined. Low-temperature plasma radiofrequency ablation (LTPRA) has been proposed as an alternative treatment for several neuropathic pain diseases.

aimTo evaluate the effect of LTPRA of SPG in treating chronic and episodic CH. MATERIAL AND

methodsThe patients with CH, who achieved temporary pain relief following SPG block, treated using LTPRA between January 2015 and October 2017 were reviewed. Seventy-six patients were included: 50 patients suffered from episodic CH and the remaining 26 patients from chronic CH. The primary outcomes were clinical improvement rate, defined as the percentage of partial and complete pain relief results at 1 day, 12 months, and 24 months of follow-up after the operation.

resultsClinical improvement rates were 92.3%, 92.3% and 73.1% in chronic CH and 73.1%, 84% and 68% in episodic CH at each follow-up time point, respectively. 3 chronic CH patients and 7 episodic CH patients showed no pain relief after the operation. Drooping eyelids were found in 2 cases, one recovered at the 3-month follow-up but another one did not in the 24-month follow-up. No serious complications occurred intraoperatively or postoperatively.

conclusionsLTPRA can be considered an effective and alternative surgical modality in treating patients with chronic and episodic CH, based on SPG block.
