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.
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
backgroundVarious studies have established a link between household fuel use and diverse health conditions. However, research examining the impact of household fuel use on migraine remains scarce. Therefore, the objective of this study was to explore the association between household fuel use and the risk of migraine, as well as the potential modifying effects of sleep duration.
methodsUtilizing a nationwide representative cohort from the China Health and Retirement Longitudinal Study (CHARLS) from 2011 to 2015, we included 9,160 participants aged 45 years and older who did not have migraine at baseline. Household fuel use was categorized into two groups: clean fuel and solid fuel. Migraine was defined based on self-reports using the ID-Migraine questionnaire. Sleep duration was classified into two groups: Non-ideal sleep duration (<7 hours/d or >8 hours/d) and ideal sleep duration (7-8 hours/d). Cox proportional hazards regression models were utilized to assess the associations of solid fuel use and sleep duration with migraine. The modifying effect of sleep duration was analyzed.
resultDuring a 4-year follow-up period, 520 migraine cases were identified. The use of solid fuels was associated with an increased risk of migraine compared to the use of clean fuels. The hazard ratio (HR) and 95% confidence interval (CI) was 1.34 (1.06-1.69) for heating and 1.29 (1.06-1.58) for cooking with solid fuels, compared to the use of clean fuels. The use of solid fuels for heating and cooking simultaneously was also associated with an elevated risk of migraine (HR: 1.53, 95% CI: 1.16-2.01), compared with the simultaneous use of clean fuels. Additionally, compared with consistent solid fuels users, those switching from solid to clean fuel and consistently using clean fuels for heating and cooking showed a decreased risk of migraine. For heating, the HR was 0.66 (95% CI: 0.49-0.90) for switching from solid to clean fuel and 0.54 (95% CI: 0.38-0.77) for consistently using clean fuels; for cooking, the corresponding HRs were 0.74 (95% CI: 0.57-0.97) and 0.68 (95% CI: 0.53-0.86), respectively. Ideal sleep duration modified the association between solid fuel use and migraine. Among individuals with non-ideal sleep duration, the use of solid fuels for heating (HR: 1.47, 95% CI: 1.09-1.97, P = 0.010) and cooking (HR: 1.31, 95% CI: 1.02-1.68, P value = 0.034) was significantly associated with an increased risk of migraine. In contrast, these associations were not statistically significant among those with ideal sleep duration (heating: HR: 1.13, 95% CI: 0.77-1.65, P = 0.537; cooking: HR: 1.28, 95% CI: 0.90-1.81, P = 0.165).
conclusionHousehold solid fuel use was associated with an increased risk of migraine, and this association was modified by ideal sleep duration. Reducing exposure to household air pollution from solid fuel use and promoting healthy sleep behaviors may help to reduce the burden of migraine in areas where solid fuel use is prevalent.
