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

The introduction of monoclonal antibodies (mAbs) against calcitonin-gene related peptide (CGRP) or CGRP receptors in the treatment of migraine raised concerns on the possible risks associated to the long-term inhibition of CGRP physiological functions. In this proof-of-concept study, we have measured the circulating levels of CGRP in 7 patients with high-frequency episodic migraine receiving the anti-CGRP receptor mAb erenumab for at least 6 months, to test the hypothesis that long-term blockade of CGRP receptors induces an increase in systemic CGRP levels via a classical up-regulation mechanism.Plasma CGRP levels were measured by a validated radioimmunoassay at baseline, and after 1 and 6 months of treatment with erenumab, 70 mg given sc every 4 weeks.We found (data expressed as the means ± SD): 38.34 ± 30.74 pg CGRP/ml of plasma at baseline, 38.19 ± 29.23 pg/ml after 1 month and 53.89 ± 28.03 pg/ml after 6 months of treatment. Thus, the average increase in plasma CGRP levels after 6 months of treatment was about + 40% compared to both baseline and 1-month treatments; such difference was not statistically significant because of high SD values in all groups.These preliminary findings need to be confirmed in larger, sufficiently powered experiments.
