well-written Materials and Methods section and followed by a well-written Discussion.
The Results need to be clearly and simply stated because it is the Results that constitute the new knowledge that you are contributing to the world. The earlier parts of the paper (Introduction, Materials and Methods) are designed to tell why and how you got the Results; the later part of the paper (Discussion) is designed to tell what they mean. Obviously, therefore, the whole paper must stand or fall on the basis of the Results. Thus, the Results must be presented with crystal clarity.
Avoid Redundancy
Do not be guilty of redundancy in the Results. The most common fault is the repetition in words of what is already apparent to the reader from examination of the figures and tables. Even worse is the actual presentation, in the text, of all or many of the data shown in the tables or figures. This grave sin is committed so frequently that I comment on it at length, with examples, in the chapters on how to prepare the tables and illustrations (Chapters 13 and 14).
Do not be verbose in citing figures and tables. Do not say "It is clearly shown in Table 1 that nocillin inhibited the growth of N. gonorrhoeae." Say "Nocillin inhibited the growth of N. gonorrhoeae (Table 1)."
Some writers go too far in avoiding verbiage, however. Such writers often violate the rule of antecedents, the most common violation being the use of the ubiquitous "it." Here is an item from a medical manuscript: "The left leg became numb at times and she walked it off. . . . On her second day, the knee was better, and on the third day it had completely disappeared." The antecedent for both "its" is presumably "the numbness," but I rather think that the wording in both instances was a result of dumbness.
