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

Moderate to severe migraine attacks are treated with triptans. However, about 25% of migraineurs fail to respond to triptans. We investigated the involvement of gene polymorphisms, personality traits and characteristics of headache, and made a scoring system for prediction of clinical response to triptans in patients with migraine. Gene polymorphisms including serotonin (5-HT)(1B) receptor G861C and dopamine receptor 2 (DRD2) C939T, personality traits and characteristics of headache were investigated in 46 consistent responders and 14 inconsistent responders to triptans. The multivariate stepwise logistic regression analysis revealed that age, periorbital/deep orbital pain and C/C genotype carrier at DRD2 C939T were significant factors that contributed independently to the negative response to triptans in patients with migraine. Their odds ratios were 6.329 (40-69 vs. 20-39 years, 95% CI 1.441-27.778), 6.772 (no vs. yes, periorbital/deep orbital pain, 95% CI 1.159-39.580) and 14.085 (non-C/C vs. C/C genotype at DRD2 C939T, 95% CI 1.253-166.667), respectively. The predictive index (PI) of clinical response to triptans in patients with migraine was calculated using these three factors. The score in inconsistent responders (1.6 ± 0.6) was significantly higher than that in consistent responders (0.8 ± 0.7, P < 0.001). Sensibility of low-score (RI = 0) group was 100%, and specificity of high-score (PI ≥ 2) group was 87%. The proposed scoring system should in the future be the object of larger studies to confirm its validity.
