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

backgroundCoronavirus disease 2019 (COVID-19) bring about a range of psychological distress and symptom deterioration to headache patients especially to some migraineurs. Compared to migraineurs or normal control, medication overuse headache (MOH) patients are more likely to experience a worse psychological distress and poorer outcome in non-COVID-19 time. However, in COVID-19 pandemic, whether MOH patients would have greater physical and mental symptom deterioration or worse relief of headache symptoms and medications overuse remained unclear. We aim to investigate the impact of COVID-19 on MOH patients to guide for a better management in this study.

methodsWe enrolled MOH patients who were diagnosed and treated at headache clinic of West China Hospital. Information of the pre-pandemic 3 months period and COVID-19 pandemic period was collected. Univariate and multivariate logistic regression were performed to identify independent factors associated with changes in headache symptoms and drug withdrawal.

resultsSeventy-eight MOH patients were enrolled into the study ultimately. In comparison to pre-pandemic period, fewer MOH patients reported decreased headache days, intensity and days with acute medications per month during the pandemic. Available access to regular prophylactic medications was significantly associated with a reduction of at least 50% in headache days and decrease in headache intensity per month with respective odds ratios of 39.19 (95% CI 3.75-409.15, P = 0.002) and 10.13 (95% CI 2.33-44.12, P = 0.002). Following abrupt withdrawal and high educational level were both significant factors in decreasing headache intensity. Male sex was significantly associated with decrease in days with acute medication per month during the pandemic (odds ratios 4.78, 95%CI 1.44-15.87, P = 0.011).

conclusionsOur findings reflect that MOH patients experienced a worse relief of headache symptoms and drug withdrawal during the pandemic. Available access to regular prophylactic medications was the significant independent factor for improvement of headache symptoms. Male sex was significantly associated with decreased days with acute medications per month.
