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

Coronavirus SARS-CoV-2 is responsible for the COVID-19 pandemic, and headache is reported in 6.5% to 34% of all cases. There is little published evidence on the pharmacological treatment of COVID-19 headache. This case series presents six COVID-19 infected patients with refractory headache in which intranasal bedside Sphenopalatine Ganglion Block was performed for analgesia. All patients had a reduction in headache intensity from severe to mild or no pain after the procedure with minor transient side effects. Proposed mechanisms of action include reduction of local autonomic stimuli, intracranial vasoconstriction, and reduction of vasoactive substances release in the pterygopalatine fossa.
