Figure 1. Mean Measurement and Treatment Research to Improve Cognition in Schizophrenia Consensus Cognitive Battery (MCCB) Cognitive Composite T Scores by Study and Visit for Patients Receiving Placebo.

Unadjusted mean MCCB cognitive composite scores are plotted by study and week of assessment through week 24. The line color denotes studies that assessed cognition at a screening visit (“Yes”) and those that began assessments at baseline (“No”). The line thickness is proportional to the study sample size, and assessment time points for each study are denoted by markers.
