The chart is only regarding RCTs. In the best individual trials that we have, it does not show a benefit for respiratory infections. But we do see some suggestion of benefit in meta-analyses. In general, if the meta-analysis shows something that is not seen in RCTs, then we probably need more evidence. But it does seem to be a real effect.
