Table 2.

Number of tweets about control diseases distributed by American media and the retweets they generated. Percentages (%) were calculated with respect to the total number of tweets or retweets distributed in the control group of diseases. Spearman rank correlation coefficients between the tweets and retweets are shown for each condition or disease along with the level of statistical significance.
