Table 1.
Comparison of baseline characteristics between Basic and Core surveys in the unmatched and matched samples.
Std. Diff, Standard difference. Continuous variables are reported as mean ± standard deviation. Categorical variables are reported as number (%).
Fig 1.
Distribution of the estimated propensity score by survey type in the original unmatched sample (top panel) and in the matched sample (bottom panel).
Solid line corresponds to Basic survey. Dashed line corresponds to Core survey.
Table 2.
Comparison of survey outcomes between Basic and Core surveys in the original unmatched sample.
All outcomes are reported as mean ± standard deviation.
Table 3.
Estimated odds ratio/relative ratio of Core Survey use, compared with the Basic Survey, in the matched sample.
The estimates are adjusted for baseline facility and survey characteristics.
