a News follows the phrasing of the press release: In ITT and AT analysis, news headlines were more likely to align to evidence if the press release phrasing did so; and in the AT analysis, claims in the news text were also more likely to do so if the press release did so. The discrepancy between ITT and AT analyses was due to a high level of condition mixing (see text). b ITT and AT analyses both show no evidence of reduced news uptake for press releases whose headlines and main claims aligned to evidence (see also Additional file 1: Figure S4 for the average number of news per press release). Error bars are 95% CIs. For each bar, n reports total number of news (a) or press releases (b) in that analysis group (i.e. the denominator of the proportion that the bar displays; total n is lower for AT than ITT analysis, because AT was possible only for press releases with causal claims present in headlines or main claims)
