Univariable and multivariable analysis: Predictors of reported TxA ≥6%.

<p>^<b>1</b> Total sample size is restricted to those who provided a TxA estimate (602); therefore individual samples are smaller than in demographics section (Supplement A3, total sample n = 667).</p><p>^<b>2</b> p = value obtained through likelihood estimates.</p><p>^<b>3</b> HIC = High-income countries, UMIC = upper-middle-income countries, LMIC = lower-middle-income countries, LIC = low-income countries.</p><p>^<b>4</b> Center volume was evaluated as ordinal, source of funding as out-of-pocket vs. others, and economic hardship as continuous variable in multivariable analysis in order to preserve power.</p><p>Univariable and multivariable analysis: Predictors of reported TxA ≥6%.
