Study index

Every study PepIndex has recorded, stored once and referenced from wherever it is relevant. Each carries its evidence type, the model it used, its sample size where reported, and what it found — including null results, which are recorded rather than quietly dropped. Each has a permalink, so a study can be cited without being retyped.
