negative constructs have no place i

negative constructs have no place in scientific writing. After all,
who can make any sense of writing that says Diet was not a risk
factor for asthma in adults but was not in children.
The meanings of sentences often become clearer when
negative words are omitted. For example, writing that We did
not find a statistical interaction between the outcome and exposure
variables could suggest that you did not even look for one.
Rather, it is clearer to write that There was no significant
interaction between the outcome and exposure variable (P = 0·91).
The direct expression and the inclusion of the P value shows
that you tested for an interaction and found that it was
statistically non-significant.
Similarly, try not to use negative sentence constructions such
as We did not find that weight loss was related to age that suggest
that you may not have tested for a relation. It is much better to
say that There was no relation between age and weight loss, which
describes exactly what you mean. In the same vein, phrases
such as We found no evidence that are often better rephrased
with We did not find any evidence that. No one can find nothing,
although you can demonstrate that something is not present.
