Multiple linear regression of *U‐PBG (μmol/mmol creatinine), model R ² = 0·308

	‡B	95% CI	P‐value
*P‐long pentraxin‐3	0·591	0·054 to 1·129	0·032
†Relative eGFR CKD‐EPI	−0·014	−0·028 to −0·001	0·036
S‐Prealbumin	−5·085	−11·357 to 1·188	0·110

The data are regression coefficients, B, in the acute intermittent porphyria cases (n = 50). *Ln‐transformed. †Relative estimated glomerular filtration rate (eGFR) calculated using the Chronic Kidney Disease Epidemiology Collaboration (CKD‐EPI) cystatin C equation. ‡B = regression coefficients; CI = confidence interval.
