Efficacy of galcanezumab in patients with migraine and history of failure to 3-4 preventive medication categories: subgroup analysis from CONQUER study.
Article in The journal of headache and pain, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03559257 (A Randomized, Double-Blind, Placebo-Controlled Study of Galcanezumab in Adults With Treatment-Resistant Migraine - the CONQUER Study), which is not on this map.

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.

Abstract
backgroundChronic migraine (CM) and episodic migraine (EM) are associated with substantial headache-related disability, poor quality of life and global societal burden. In this subgroup analysis from the CONQUER study, we report efficacy outcomes from a pre-specified analysis of galcanezumab versus placebo in patients with CM or EM and 3-4 prior preventive medication category failures due to inadequate efficacy (after at least 2 months at maximum tolerated dose), or safety or tolerability reasons. The patient population is of particular interest due to evidence of decreased quality of life and increased economic burden among patients with migraine that is inadequately managed and is of interest to decision-makers globally.
methodsKey outcomes included overall mean change from baseline in monthly migraine headache days and proportions of patients achieving ≥30% (CM), ≥50%, and ≥ 75% reduction (response rates) in monthly migraine headache days across Months 1-3. Patient functioning and disability were evaluated at Month 3.
resultsOf the 462 randomized patients, 186 (40.3%) had a history of 3-4 preventive category failures. Galcanezumab versus placebo resulted in significantly (P ≤ .001) larger overall mean reduction in monthly migraine headache days (total: - 5.49 versus - 1.03; CM: - 6.70 versus - 1.56; EM: - 3.64 versus - 0.65). Similarly, the ≥50% response rate was significantly (P ≤ .001) higher with galcanezumab versus placebo (total: 41.0 versus 12.7; CM: 41.5 versus 8.4; EM: 41.1 versus 16.5). In the CM group, the ≥30% response rate was significantly higher in the galcanezumab group than the placebo group (CM, 57.5 versus 19.8, P ≤ .0001) as was the ≥75% response rate (13.3 versus 2.6, P ≤ .05). Galcanezumab also resulted in significant (P < .0001) improvements in patient functioning and reductions in disability.
conclusionsGalcanezumab was effective in a difficult-to-treat population of patients with CM or EM who had failed 3-4 prior preventive medication categories.
