When the review of systems is negative, the patient generally has no particular complaints other than those offered in the history of present illlness.
It means your health care provider recorded all of the abnormal findings from the review of systems (your symptoms) in the section called HPI, and had nothing to add in the section of the chart called ROS (review of systems).
I am not entirely sure what you mean by "safe"; but if someone is PAID specifically to write a positive review, or a negative review, then of course such a review is not trustworthy.
Review Of SystemsROS stands for "review of systems." It's the part of the medical history at a visit in which the clinician asks you about recent signs and symptoms.Review of SystemsReview of Systems

IN statistics yes there is a negative mean. Mean is the average of multiple numbers. Negative is opposite of positive.
A negative plus a negative equals a negative.
its negative! negative reply, answer that is not positive
Yes, the mean of a set of negative numbers is always negative. The mean is calculated by summing all the numbers and then dividing by the count of numbers. Since all the numbers in the set are negative, their sum will also be negative, resulting in a negative mean.
Yes, oral sex is medically safe if you use a condom. It is medically unsafe if a person has HIV-AIDS or an STD. However, since many STDS and HIV-AIDS often do not show symptoms, just the absence of symptoms does not mean a man is medically 'clean' and therefore, oral sex without protection is technically never 'safe'.
