These biases overestimate the efficacy of psychiatric treatments for schizophrenia and bipolar disorder. The researchers specifically examined clinical trials funded by the Stanley Medical Research Institute with which they are affiliated.
Their findings challenge the validity of the evidence base on which psychiatrists make clinical decisions:
‘We conclude that publication bias and outcome reporting bias are common in papers reporting RCTs in schizophrenia and bipolar disorder. These data have major implications regarding the validity of the reports of clinical trials published in the literature.‘

For instance, it is important that disconfirming evidence, such as evidence that a treatment has failed to result in improvement, is published and considered. Otherwise, publication bias gives rise to distorted claims of efficacy, as has been demonstrated in the research on treatment for depression (see MIA report).
