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 objective of the study is to systematically review the efficacy and safety of frovatriptan (F) versus rizatriptan (R), zolmitriptan (Z) and almotriptan (A), through a pooled analysis of three individual studies. 414 subjects with a history of migraine with or without aura (IHS criteria) were randomized to F 2.5 mg or R 10 mg (study 1), F 2.5 mg or Z 2.5 mg (study 2), and F 2.5 mg or A 12.5 mg (study 3). The studies had an identical multicenter, randomized, double blind, cross-over design, with each of the two treatment periods lasting not more than 3 months. The number of pain free (PF) and pain relief (PR) episodes at 2 h, and the number of sustained pain free (SPF) and recurrent episodes within the 48 h were the efficacy endpoints. 346 patients were included in the intention-to-treat analysis. Rate of PF episodes at 2 h was 30% with F and 34% with comparators (p = NS). PR episodes at 2 h were 55% for F and 59% for comparators (p = NS). SPF episodes at 48 h were also similar between the two groups (22% F vs. 21% comparators). Rate of recurrence was significantly (p < 0.001) lower under F (27 vs. 40% comparators). Drug-related adverse events were significantly (p < 0.05) less under F, particularly cardiovascular symptoms. Our systematic analysis of individual studies suggests that F has a similar immediate efficacy, but a more sustained effect and a better tolerability than R, Z and A.
