Effect of a one-time chocolate ingestion on the mean number of noninflammatory lesions (comedones) at 3 time points (baseline, Day 4, and Day 7). There were significant increases from baseline for Days 4 (p=0.009) and 7 (p=0.042). For Day 4 compared to Day 7, statistical significance was not achieved (p=0.310).

The medium-strength positive Pearson correlation coefficient between the amount of chocolate each subject consumed and the number of lesions each subject developed on Day 7 (r=0.314) and the small correlation for total lesions developed and amount of chocolate consumed between baseline and Day 4 (r=0.250). The blue diamond represents the total number of acneiform lesions a subject had on Day 4. Red squares represent the total number of acneiform lesions a subject had on Day 7.

Effect of a one-time chocolate ingestion on the mean number of inflammatory lesions (papules, pustules, nodules) at 3 time points (baseline, Day 4, and Day 7). There was a significant difference from baseline to Day 4 (p=0.008), but not from baseline to Day 7 (p=0.151). For Day 4 compared to Day 7, statistical significance was not achieved (p=0.150).

Effect of a one-time chocolate ingestion on total mean number of acneiform lesions (comedones, papules, pustules, nodules) at 3 time points (baseline, Day 4, and Day 7). A statistically significant increase in the mean number of total acneiform lesions (comedones, papules, pustules, nodules) was detected on both Day 4 (p=0.006) and Day 7 (p=0.043) compared to baseline. Statistical significance was not achieved when mean number of acneiform lesions on Days 4 and 7 were compared to each other (p=0.138).
