Correlations
Casia Pentacam
Casia Pearson Correlation 1 .433** (p-value)
Sig. (2-tailed) .006 (r-value)
N 39 39
Pentacam Pearson Correlation .433** 1
Sig. (2-tailed) .006
N 39 39
Can someone please describe what these value show and what they mean? Thank you ever so much.

casia and pentacam has a pearson correlation coefficient of 0.433 and this coefficient is significant(0.006). As the coefficient increase this means that the linear relationship is higher between casia and pentacam values. Lower values of coef. mean that the relationship is approachin to non-linear. Pearson correlation coefficient only gets values between 0-1.

Better output of your results could get better results...

Thankyou for your reply, could you explain why it is termed significant at a value of 0.006?

Significance is based on your p-value and in your case it is 0.006. In order to have a significant statistic your p-value should be below the alpha value. Alpha-value is mostly accepted as 0.05 in the medical community (the only area that I'm aware of). Thus, in your case p-value(0.006) is below alpha value(0.05) and this can be stated statistically as: Reject null hypothesis! (which means coefficient equals to 0, and we reject this), and this is statistically significant(because p is below alpha).
