the aim of this study is to validate the accuracy and precision of social media methodology and conduct evaluations of twitter adr reporting for commonly used pharmaceutical agents. faers and twitter shared similarities in types of data reported and a few unique items to each data set as well. comparative studies suggested the practicality of using social media as a complementary resource and demonstrated a moderate agreement on adr data between social media and faers [10,11]. twitter was selected as the social media for evaluation thanks to its simplicity and timeliness in information sharing and access. searchability and generalizability were the main factors in selecting twitter as the social media platform. a chi-square test was used to statistically quantify the difference in adrs between the faers data and twitter data.
following the matching, a chi-square test was performed to test nonsignificant differences in the relative frequencies of an adr between faers data and twitter data. in 2017, mackinlay et al  evaluated adrs of 3055 drugs on twitter and found that twitter had up to 72% precision of adr detection. in this study, 10 drugs were identified, and adr reports of these drugs on twitter were retrospectively obtained by searching for tweets containing the drug names that mentioned adr experiences. the sample size of tweets obtained for the drugs was relatively small compared with that of faers reports from march 1, 2016, to march 31, 2017. the sample size could be largely increased in future studies as twitter contains a large collection of tweets. to demonstrate the accuracy and usability of social media adr data in complementing faers, future studies may benefit by using a larger sample of data, including specific drugs, and assessing multiple social media platforms. bindicates a p value above .05, leading to the failure of rejecting the null hypothesis and indicating that there is no difference in adr frequency reported between faers and twitter.
