Citation Preceding Space

error

"CT angiography is the standard modality for identifying intracranial aneurysms. MRI with vessel wall imaging (VVI) can be used for assessing culprit aneurysms in the setting of patients with acute SAH and multiple aneurysms on CTA¹¹."

Line 50:241 · Citations must have a preceding space, e.g. needs evidence <sup>2</sup>. '<sup>11</sup>'

En Dash

error

"Digital subtraction angiography remains the gold standard for identifying ruptured aneurysms causing SAH and has a specific role as second-line imaging following a negative CTA (as indicated in guidelines). The diagnostic yield of DSA after a negative CTA has been reported to be ~7.5% (range 4–13%) ¹⁰."

Line 74:298 · Use a hyphen-minus ('-') instead of an en-dash ('–').

List Caps

warning

"Japanese population"

Line 11:8 · In general, we don't start a list item with a capital letter. Exceptions are proper nouns.

Acronyms

warning

"ACOM (~35%): septum pellucidum, interhemispheric fissure and intraventricular, inferior frontal lobe (intraparenchymal)"

Line 54:11 · 'ACOM' has no definition. Spell it out if it's unfamiliar to the audience.

"PCOM (~35%): Sylvian fissure, medial temporal lobe (intraparenchymal)"

Line 55:11 · 'PCOM' has no definition. Spell it out if it's unfamiliar to the audience.

"PICA: foramen magnum"

Line 60:11 · 'PICA' has no definition. Spell it out if it's unfamiliar to the audience.

Ranges

warning

"Mortality from the first rupture is between 25-50%, with repeat bleeding a common complication in survivors. With each recurrent bleed, the prognosis worsens. In the first few days following a subarachnoid haemorrhage, there is an increased risk of additional ischaemic injury from the reactive vasospasm of the surrounding vasculature ⁵."

Line 79:40 · Don't add words such as 'from' or 'between' to describe a range of numbers.

Inline EG

suggestion

"focal neurological deficits (e.g. sensory loss, weakness, memory loss, language difficulties)"

Line 22:36 · Consider replacing a bracketed e.g. with an inline e.g. after a comma.

Semicolons

suggestion

"DSA can be particularly useful in the setting of early aneurysm thrombosis. Thrombosed aneurysms may be occult on initial CTA and DSA, yet carry the risk of recanalisation over days to weeks; for this reason, a negative early repeat study cannot definitively exclude a small thrombosed ruptured aneurysm ¹⁰."

Line 75:194 · Use semicolons judiciously.
