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

Postcraniotomy and posttraumatic headaches can result in scars generating local pain or referred pain following a neuropathic pattern. One hypothesis is that the pain can be caused and maintained by scar neuromas, developed after the nerve injury during the surgical process or trauma. This study reports two patients with chronic unilateral headaches: the first one with a posttraumatic scar in the parietal region and the other with a postsurgical scar in the mastoid region. In both patients, the headache was ipsilateral to the scar, suggesting primary headaches (trigeminal autonomic cephalalgia (TAC), as hemicrania continua and chronic cluster headache). Pharmacological treatment for these conditions failed. Instead, there was complete remission of the headache with anesthetic blockade of scar neuromas (demonstrated by clinical examination in both patients). An active search for traumatic or nontraumatic scars is recommended in all patients with refractory unilateral headaches, and anesthetic blocks for scar neuromas can be effective in treating this pain.
