"under 10: if a number is 10 or less, use full text, e.g. four"
"over 10: if a number is over 10, use digits, e.g. 5000"
"leading number is required, e.g. 0.05 not .05 including numbers where their value cannot exceed 1.0 e.g. p-values"
"fractions: no spaces either side of the slash, e.g. 1/4, 1/2 and avoid ¼, ½, etc."

"fractions: no spaces either side of the slash, e.g. 1/4, 1/2 and avoid ¼, ½, etc."
"When ranges are included there should be no space on either side of the dash, e.g. "22-27". If the range is described within prose, there should be no dash, e.g. "the mean length is between 10 and 15 centimetres", not "the mean length is between 10-15 cm". Notice too, that the unit should be included in full if used in prose."
"Some biomedical classification systems and nomenclatures employ Roman numerals (e.g. I, II, III...) instead of Arabic numerals (e.g. 1, 2, 3...). The most well-known usage is probably the numbering of the cranial nerves, which are designated I through XII 2. The Bosniak classification of cystic renal masses also uses Roman numerals 3."

"Also, see units of measurement for further specific details on various units, but in general we prefer the use of SI units on Radiopaedia.org, as per best scientific practice."
"where a per cent sign is used, it should not have a preceding space, e.g. "22%""
"where an operator is used, it should not have a space after it, e.g. ""
"when the tilde '~' is used, it should not have a space after it, e.g. "~15""

"Numbers, units and operators are used frequently in articles. We often quote the incidence of a condition as a range or say that x happens in more than y% of cases."
