How to design tables 43

This table is from a paper of which I was a coauthor. Now, with the benefit of hindsight, I see that this title contains the common error of repeating every single heading, except, in this case, the first one.No fewer than 31 of the 39 words in the title can be deleted. The shortened version can be grasped at a glance:

Table 8.1 Details of 80 diagnostic cases of first-trimester chorionic biopsy

The declarative title

If a table shows a clear trend or relationship, a declarative title could be preferable. The following table shows that the frequency of fractured clavicles increased with increasing birth weight.

Table 8.2 Fractured clavicles and birth weight

Deliveries Fractured claviclesBirth weight, g n % n %

But the title is neutral and one has to study the table for a while in order to grasp the message. It would have helped the reader if the table’s message had been stated in the title:
