Forest plot of crude and adjusted absolute risks of (A) collagen and (B) neurological AESIs. Collagen AESIs comprised tendon rupture, aortic aneurysm with or without dissection, retinal detachment, uveitis, and a composite category for all collagen AESIs. Neurological AESIs comprised CNS AESIs (seizures/convulsions, intracranial hypertension, psychosis/delirium, and altered mental status/encephalopathy), PNS AESIs (muscle weakness, paresthesia/sensory disturbance [tingling, numbness, burning pain, and allodynia], gait dysfunction, and peripheral neuropathy), and a composite category for all CNS and PNS AESIs. AESIs, adverse events of special interest; CNS, central nervous system; FQ, fluoroquinolone; NTF, nitrofurantoin; PNS, peripheral nervous system; sIPTW, inverse probability of treatment weighting; SXT, trimethoprim/sulfamethoxazole.
