Quoting from your link: "We recorded the outcomes as close to 8 weeks as possible for all analyses. If information at 8 weeks was not available, we used data ranging between 4 and 12 weeks (we gave preference to the time point closest to 8 weeks; if equidistant, we took the longer outcome)." By no means does that say anything about the "long term" effects.
