Three content-validated questionnaires were used to collect AE information: two completed by the patient (pre-treatment [T\n                    <jats:sub>0<\/jats:sub>\n                    ] and 2\u20137 days post-treatment [T\n                    <jats:sub>2<\/jats:sub>\n                    ]) and one completed by the provider immediately post-treatment [T\n                    <jats:sub>1<\/jats:sub>\n                    ]. Any new or worsened symptom was considered an AE and further classified as mild, moderate, severe or serious. From the 42 participating providers (31 chiropractors; 11 physiotherapists), 3819 patient visits had complete T\n                    <jats:sub>0<\/jats:sub>\n                    and T\n                    <jats:sub>1<\/jats:sub>\n                    assessments. The patients were on average 50\u00b118 years of age and 62.5% females. Neck\/back pain was the most common presenting condition (70.0%) with 24.3% of patients reporting no condition\/preventative care. From the patients visits with a complete T\n                    <jats:sub>2<\/jats:sub>\n                    assessment (n = 2136 patient visits, 55.9%), 21.3% reported an AE, of which: 7.9% were mild, 6.2% moderate, 3.7% severe, 1.5% serious, and 2.0% had missing severity rating. The most common symptoms reported with moderate or higher severity were discomfort\/pain, stiffness, difficulty walking and headache. This study provides valuable information for patients and providers regarding incidence and severity of AEs following patient visits in multiple community-based professions. These findings can be used to inform patients of what AEs may occur and future research opportunities can focus on mitigating common AEs.\n                  <\/jats:p>","DOI":"10.1371\/journal.pone.0309069","type":"journal-article","created":{"date-parts":[[2024,8,19]],"date-time":"2024-08-19T13:23:30Z","timestamp":1724073810000},"page":"e0309069","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":11,"title":["What\u2019s the harm?
