In CSE style, the author's last name is first, followed by initials. No commas are used to offset the author's last name from his or her initials, no space separates the first and middle initial, and periods do not, in general, follow initials. For sources with two to ten authors list all authors; sources with more than ten authors list the first ten followed by et al. When there is no author given, skip the author and start with the title of the source.
Example: Losos JB. Evolution: a lizard's tale. Sci Am. 2001 Mar; 284(3): 64-69.
In CSE style, titles of periodicals (newspapers, journals, magazines) are capitalized as they normally are with the important words capitalized; book and article titles have only the first word of the title and proper nouns capitalized. You will not use italics for periodical or book titles, which differs from other citation styles you may be accustomed to.
Journal titles must be abbreviated in citations in CSE style. Rules for journal abbreviation are complex and the correct abbreviation is not always obvious. The List of Title Word Abbreviations is a searchable database of words commonly found in titles and their correct abbreviations. Additionally, a list of journal titles and their abbreviations may be found at ISI Web of Science.
Citations are presented in the order in which they are introduced in the text (not alphabetically). This means that the work that is cited first in the text (and thus assigned the number "1") appears in the list first, the work assigned the number "2" appears next, and so on.
No effective treatments are available, apart from hydration, oxygen, and upper airway suctioning if needed.1 Noninvasive CPAP has been proven to be effective as a respiratory support in moderate
to severe bronchiolitis 2 to avoid invasive ventilation by decreasing respiratory muscles upload.

CSE style does not specify a preferred line spacing in bibliographies. Instead, this decision is left at the publisher's (or your instructor's) discretion.
