TACIT has been developed by a working group of members with expertise in trial and systematic review methodology, conflicts of interest and medical publishing. TACIT is developed under the auspices of the Cochrane Bias Methods Group.
TACIT development was informed by four supporting projects and a preliminary version of the tool was user tested in 2022-23 (see below for additional details). An unpublished version of the tool was released in September 2025 for a phase of user feedback. The final version is expected to be submitted for publication in early 2026.
The TACIT website features updates about TACIT development and relevant publications.
