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

introductionFor the most part, migraine afflicts young women who often need to use the hormonal contraceptive method.

objectiveTo evaluate the effects of using exogenous estrogen, present in combined hormonal contraceptives (CHC) and progestin-only methods on the prevalence of allodynia in women with migraine.

methodsStudy comprising women diagnosed with migraine, with or without aura, who were not pregnant, breastfeeding, or menopausal. The study was conducted via the digital platform. Data were collected relating to demographics, contraceptive method, anthropometric information, smoking habits, and migraine-related symptoms. The participants then answered the following validated, self-administered questionnaires: Migraine Disability Assessment (MIDAS), Allodynia Symptom Checklist, Generalized Anxiety Disorder (GAD-7), and Beck's Depression Inventory (BDI). In order to determine the variables associated with allodynia, two binary logistic regression models were used.

resultsFour hundred eighty-six women took part in the study. Of these, 205 used CHC, 89 used a progestin-only method, and 192 participants did not use any form of hormonal contraception. Allodynia was identified in 411 (84.6%) participants. Allodynia was linked to the presence of aura (OR = 2.76; CI 95% 1.55-4.91; p = 0.001), menstrually related migraine (OR = 2.14; CI 95% 1.28-3.57; p = 0.004), greater disability (MIDAS score 23 vs. 8; p < 0.001), depression (BDI score 14 vs. 10; p < 0.001), and anxiety (GAD-7 score 11 vs. 8; p < 0.001). In adjusted analysis, CHC was associated to protection against allodynia when jointly evaluated all CHC regimens (OR = 0.49 CI 95% 0.26-0.92; p = 0.028), as well as oral CHC individually (OR = 0.48 CI 95% 0.25-0.92; p = 0.027).

conclusionCHC reduced the chances of women with migraine getting allodynia.
