Chapter 10 Reporting Guidelines

While writing journal articles or reports, what are the components we should report?

10.1 Discipline-specific Reviews

  • Propensity score matching most popular
  • Guidelines available for some discipline-specific areas:

10.2 Suggested Guidelines

Population Be specific about population of interest
- ATT vs. ATE
- exclusion criteria
Intervention Be specific about exposure
- no multiple version of treatment
- no interference
- comparator
Covariates How variables are selected
- Any important variables not measured? Proxy?
- Large list of covariates? See King and Nielsen (2019)
PS Model Model selection
- interaction or polynomials
- logistic vs. machine learning
- Residual imbalance and refit PS model
PS approach Why PS matching (or other approach) was selected?
Sample size Reduction % of the matched data: major issue!
Diagnostics Overlap vs. balance assessments
- numeric and visual
Software Report software, packages

10.3 Additional topics

Some of the advanced topics not covered here.

Sensitivity analysis - unmeasured confounding: proxy, or how much of an effect of unmeasured confounder necessary to nullify the results (e-value)
- any positivity issue? Deleting extremes has consequences!
- ad-hoc methods: truncation / trimming: bias-variance trade-off
- different matching methods and allowing different thresholds: caliper, ratio, WR/WOR
Subgroup analysis Refit within each group for matching
- See Ali et al. (2019), Rassen et al. (2012), Radice et al. (2012), Kreif et al. (2012), Green and Stuart (2014), Girman et al. (2014), Eeren et al. (2015), Wang et al. (2018), Liu et al. (2020), Dong et al. (2020) for a more complete list
Missing data Report clearly about missing data
- how missing data handled
