G

Gender/sex
  • Gender is a cultural term and sex is a biological term. Raise a query to check with the authors whether ‘gender’ should be changed to ‘sex’ or vice versa. This may depend on the context—gender may be more appropriate in some psychological or sociological contexts. In addition, the authors should report the demographics as they’ve been collected, so if the original data are collected as self-reported gender, then the authors would need to continue to use this term. It is possible that someone who identifies as a women (gender) may also be male or intersex (sex) and vice versa. Note also that, when referring to gender, the terms ‘women/men’ are preferable to ‘female/male participants’

  • The choice of may or might can change the meaning: Changing the insulin regimen might have saved the patient (the patient is dead, but if the insulin regimen had been changed, it is possible that the patient would have survived).

T

That / which
  • A restrictive (or defining) clause ‘completes’ the subject and is consequently indispensable. By contrast, a non-restrictive (or commenting) clause does no more than give additional information. A non-restrictive clause should be within commas, a restrictive one should not
  • ‘That’ introduces a restrictive clause (This is the house that Jack built); ‘which’ introduces a non-restrictive clause and is offset by commas (This house, which Jack built, was of shoddy construction)
Trend/tendency
  • Use of the terms ‘trend’ or ‘tended to’ should not be used to describe data that do not reach the threshold for significance. If authors have used these terms without clarifying the significance level or including p values, a query should be raised. Note that the term ‘trend’ is fine in connection with p for trend, or where discussing changes over a time course.

It can be legitimately extended to mean making the most practical use of something (‘Although the hills were steep, the rice farmers utilised every square inch of the land’), and is used in certain biological contexts such as ‘glucose utilisation’; in most other senses ‘use’ is better
