NAC might help reduce OCD symptoms more than placebo after 10 weeks, but the difference wasn't quite big enough to be considered statistically significant.

Scientific Claim

N-acetylcysteine (NAC) added to citalopram shows a trend toward improving overall OCD symptom severity at week 10, with a mean difference of 8.4 points between groups (P=0.06), though this did not reach statistical significance.

Original Statement

The mean difference was not statistically different between the two groups at weeks 4 and 8 (P = 0.3, and P = 0.1, respectively). However, there was a trend for statistically significant difference between the two groups in the mean difference of YBOCS at week 10 (P = 0.06).

Assessment Explanation

The study design supports causal inference, but the small sample size and high dropout rate limit precision. The study states 'trend for statistically significant difference' which is appropriate for this finding.
