Moreover, this study further advances the methodological literature on extracting, filtering, and analyzing Twitter data for monitoring public debates using web discourse data.
We examined tweets within the time span of January 1, 2020, to January 31, 2022, using the Tweets KB [22] pipeline. Tweets KB is a large-scale knowledge base of annotated tweets harvested using the Twitter streaming application programming interface (API).

Apart from large social media platforms (eg, Facebook, Meta Platforms Inc or X, formerly Twitter, X Corp) [17], the messaging app Telegram (Telegram FZ-LLC) has shown particular potential for spreading false health information through a combination of circumstances [18-20]. Telegram’s channel function allowed individuals to address a large, public audience. In such channels, creators can post content that is accessible to a potentially unlimited number of subscribers, who can join freely [21].

Global Influence of Cannabis Legalization on Social Media Discourse: Mixed Methods Study
A systematic review that analyzed the advantages and disadvantages of using Twitter in public health research concluded that it is a valuable tool for identifying social concerns and information needs on a given topic [12,13]. Previous studies have demonstrated the effectiveness of content analysis as a public health tool for analyzing and studying issues related to drugs [14-17].

For instance, Health Map combines formal sources such as the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) with informal data sources such as Twitter to reduce reporting delays [4]. A study on the 2010 cholera outbreak in Haiti assessed the correlation between unofficial data sources (eg, Health Map and Twitter) and government-reported cases. The effective reproduction number was also estimated using these nonofficial sources [5].

To address the gaps described between HCPs and the general population throughout the pandemic, we analyze the emotions of a matched sample of HCPs and non-HCPs from a high-quality Twitter Panel dataset [25,26], selecting users who tweeted consistently throughout the study period from January 2019 to May 2022. The prepandemic period enables us to control for baseline differences.

X (formerly known as Twitter) provides real-time insights into the thoughts, feelings, and conversations of millions of users. Natural language processing (NLP) tools are instrumental in analyzing social media content, offering deeper insights into public perception. NLP methods enable the analysis of public sentiment toward specific topics, the detection of emerging trends, and the identification of demographic groups participating in these discussions.

In particular, Twitter (now rebranded as X, though “Twitter” is used in this article given its widely recognized name) has over 600 million monthly active users [5] and has gained traction across clinical subspecialties, journals, and academia for research dissemination [6-8]. Having a Twitter presence is becoming increasingly important as a means to reach target audiences and affect bibliometric markers of research impact.

The number of social media users escalates globally [20], with nearly 50% of Japan’s population using Twitter (now X), a leading text-based social media platform [21].

Social media platforms, such as X (formerly Twitter), can foster collaboration, mentorship, and promotion of research [5,6]. However, studies examining X’s impact on existing gender gaps are limited. In this study, we aimed to analyze differences between X users and non–X users and differences in X use by gender among adult cardiologists.
This cross-sectional study was exempt from ethical approval by the Cedars-Sinai institutional review board due to the use of publicly available data.
