These are both the same report, and it is not conclusive (which the authors agree on). There are many issues with the report, but one is that as it wasn't pre-registered and due to its exploratory nature, it's highly sensitive to accidental p-hacking.
Until a completely new sample of victims with no relation is taken and the study replicated against a completely new control group with no relation, it has very little value. And even if it did, it still wouldn't be conclusive - psychosomatic illness can have physiological effects.
The only way is to prove the mechanism of the attack - which for microwave attacks is readily done with wearable RF devices - and to find a physiologically plausible mechanism for that exact observed attack. Which should be pretty easy to do, and which the CIA hasn't done.
