Caption of a Figure, Table, Etc.

Container element for the textual description that is associated with a <fig>, <table>, etc. This is the title for the figure or the description of the figure that prints or displays with the figure.

In print or on display, a caption is usually recognizable because it is not part of the ordinary text flow; it sits just under, above, beside, or in the same small window or page area as the tabular portions of the table or the graphical portions of the figure.


<caption> contains the entire, visible textual description of a table, figure, or similar object, but does not typically include the figure or table number, since this will typically be generated on display. If needed in the text, such numbers will be tagged as <label>s. The text of the caption includes any separately tagged <title> and as many paragraphs of information as needed. It may include legends, which are not identified as a separate element in this Suite.

Conversion Note: In many journal articles, a distinction is made between the caption of a figure/table/etc. and its title. There may be two separate tags (<caption> and <title>), or the first sentence of the caption may be set off typographically from the rest of the caption to indicate that it is a title, for example, the first sentence may be italic or bold. In either case, if it is obvious that the figure/table/etc. contains both a title and a caption, both the title and the caption should be tagged during conversion, and the title should be moved inside the caption if it is outside.

Example 1

In a figure:

<p>We identified .... Details of randomization procedures, 
treatment schedules, and numbers of patients followed up 
are given on the <italic>BMJ</italic> website.</p>
<fig id="F1"> 
<label>Figure 1</label> 
<title>Deaths Among Patients Receiving Day Hospital 
Care or Alternative Services.</title>
<p> Odds ratios of death by end of follow up were calculated 
by fixed effects model. Heterogeneity between trials is 
presented as &amp;#x03C7;<sup>2</sup></p>

Example 2

In a table:

<table-wrap id="TN0.170"> 
<label>Table 17</label>
<caption><p>Numbers of patients receiving institutional 
care at the end of scheduled follow up and use of hospital 
beds among those allocated to day hospital or alternative
<th colspan="3" align="center" rowspan="1">Institutional 
<th align="left"/> <th colspan="2" align="center"
rowspan="1">&#x2003;Bed use (days)</th>

<p>Functional and evolutionary relationships between
polyadenylation machineries and telomerases. The
functional relationships described here are shaded.</p>
<caption specific-use="long">
<p>Functional and evolutionary relationships between
polyadenylation machineries and telomerases. The thick
rectangular frame encompasses the Hfq and PABP II
polyadenylation stimulatory factors. Hfq and PABP II are
linked to enzymes that they modulate by thin rectangular
frames. Members of the nucleotidyltransferase family are
surrounded by an oval, and telomerase-related enzymes
that maintain the 5&#x2032; extremities of RNA tagged
by a hairpin structure are circled. The functional
relationships described here are shaded.</p>
