“…To assess the heterogeneity of the effect estimates, the I 2 statistics classification by Higgins et al (2003) was employed [ 15 ]. Heterogeneity was categorized as moderate ( I 2 -value 50–75%) or considerable ( I 2 -value > 75%), indicating significant heterogeneity [ 16 ]. If the heterogeneity exceeded 50%, the random effects method was used; otherwise, the fixed effects method was employed.…”

Background Epilepsy, characterized by recurrent unprovoked seizures, poses significant challenges to affected individuals globally. While several established risk factors for epilepsy exist, the association with cigarette smoking remains debated. This study aims to conduct systematic review and meta-analysis to elucidate the potential association between smoking and the likelihood of epilepsy. Methods The search was performed on March 31st, 2023, using the Medline, Embase, Web of Science, Scopus, and ScienceDirect. We included cohort, cross-sectional, and case–control studies in our meta-analysis, conducting subgroup analyses based on smoking history, sex, and epilepsy type to yield specific insights. Results We identified 2550 studies, of which 17 studies were finally included in this study. The pooled odds ratio of epilepsy was 1.14 (0.96–1.36) in smokers compared to non-smokers. In current smokers compared to non-smokers, the odds ratio was 1.46 (1.13–1.89), while, in former smokers compared to non-smokers, the odds ratio was 1.14 (0.83–1.56). Conclusions While the overall association between smoking and epilepsy did not reach statistical significance, a notable association was found among current smokers. The study emphasizes the importance of smoking cessation as a potential preventive measure against epilepsy, especially given the proconvulsive effects of nicotine. Future research should address limitations and explore specific clinical scenarios to enhance our understanding of the complex relationship between cigarette use and epilepsy. Systematic review registration CRD42022342510.

“…We assessed the heterogeneity of effect estimates using the classification of I 2 statistics as outlined by Higgins et al 19 We considered an I 2 -value in the range of 50%-75% as indicative of moderate heterogeneity and an I 2 -value exceeding 75% as considerable heterogeneity. 20 In cases where heterogeneity exceeded 50%, we applied the random effects method; otherwise, we used the fixed effects method. The meta-analysis was conducted utilizing the Review Manager 5.4 software provided by Cochrane, with forest plots generated for a clear visualization of pooled ORs.…”

SummaryThe association between psoriasis and alcohol consumption has been inconsistent across various studies. However, to the best of our knowledge, no dose‐response meta‐analysis has been performed to date. This study aims to investigate the association between alcohol consumption and psoriasis. The search was performed on July 27, 2021, using Embase and MEDLINE. The restricted cubic spline analysis was used to perform a dose‐response analysis. We identified 3,904 studies, of which 48 studies with 1,702,847 individuals across 24 countries were included. Alcohol consumption was positively associated with psoriasis (odds ratio [OR], 1.47; 95% confidence interval [CI], 1.27‐1.70). In addition, a significantly increased OR for psoriasis was observed in males (OR, 1.84; 95% CI, 1.13–3.01) but not in females (OR, 1.22; 95% CI, 0.97–1.54). Based on eight studies, including three cohort and five case‐control studies, the analysis revealed that with each additional gram of daily alcohol intake, the OR for psoriasis increased by 4%. We found a positive association between alcohol consumption and psoriasis. The association is more prominent in the group drinking more than 45 g of alcohol per day (3.2 alcoholic drink equivalent).

Die Metaanalyse wurde mit der Review Manager 5.4 -Software von Cochrane durchgeführt, mit Forest plots zur klaren Visualisierung der zusammengefassten OR.…”

ZusammenfassungVerschiedene Studien zur Assoziation zwischen Psoriasis und Alkoholkonsum ergeben kein einheitliches Bild. Nach unserer Kenntnis wurde allerdings bisher noch keine Metaanalyse zur Dosis‐Wirkungs‐Beziehung durchgeführt. Diese Studie untersucht die Assoziation zwischen Alkoholkonsum und Psoriasis. Die Datenbanksuche wurde am 27. Juli 2021 in den Datenbanken Embase und MEDLINE durchgeführt. Zur Analyse der Dosis‐Wirkungs‐Beziehung wurde die Restricted‐cubic‐Spline‐Analyse eingesetzt. Insgesamt konnten wir 3904 Studien identifizieren, von denen letztlich 48 mit einer Gesamtpopulation von 1 702 847 Personen in die Metaanalyse einbezogen wurden. Alkoholkonsum war positiv assoziiert mit Psoriasis (Odds Ratio [OR] 1,47; 95%‐Konfidenzintervall [KI] 1,27–1,70). Außerdem fand sich eine positive OR für Psoriasis bei Männern (OR 1,84; 95% KI 1,13–3,01), nicht aber bei Frauen (OR 1,22; 95% KI 0,97–1,54). Auf der Basis von acht Studien (drei Kohortenstudien und fünf Fall‐Kontroll‐Studien) ergab die Analyse, dass sich für jedes zusätzliche Gramm an täglichem Alkoholkonsum die OR für Psoriasis um 4% erhöht. Wir konnten eine positive Assoziation zwischen Alkoholkonsum und Psoriasis feststellen. Diese Assoziation ist deutlicher in der Gruppe von Personen, die täglich mehr als 45 Gramm Alkohol zu sich nehmen (dies entspricht täglich 3,2 Gläsern eines alkoholischen Getränks).
