However, existing data were mostly restricted to suicide risk, focused on lithium and valproate and rarely adequately adjusted for potential confounders. This study aimed to assess comparative mortality risk with all, natural and unnatural causes between lithium, valproate and three frequently prescribed second-generation antipsychotics (SGA), with adjustment for important confounders.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S2045796024000337_sec2b\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      This population-based cohort study identified 8137 patients with first-diagnosed BD, who had exposed to lithium (\n                      <jats:italic>n<\/jats:italic>\n                      = 1028), valproate (\n                      <jats:italic>n<\/jats:italic>\n                      = 3580), olanzapine (\n                      <jats:italic>n<\/jats:italic>\n                      = 797), quetiapine (\n                      <jats:italic>n<\/jats:italic>\n                      = 1975) or risperidone (\n                      <jats:italic>n<\/jats:italic>\n                      = 757) between 2002 and 2018. Data were retrieved from territory-wide medical-record database of public healthcare services in Hong Kong. Propensity-score (PS)-weighting method was applied to optimize control for potential confounders including pre-existing chronic physical diseases, substance\/alcohol use disorders and other psychotropic medications. PS-weighted Cox proportional-hazards regression was conducted to assess risk of all-, natural- and unnatural-cause mortality related to each mood-stabilizer, compared to lithium. Three sets of sensitivity analyses were conducted by restricting to patients with (i) length of cumulative exposure to specified mood-stabilizer \u226590 days and its medication possession ratio (MPR) \u226590%, (ii) MPR of specified mood-stabilizer \u226580% and MPR of other studied mood-stabilizers &lt;20% and (iii) monotherapy.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S2045796024000337_sec3c\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Incidence rates of all-cause mortality per 1000 person-years were 5.9 (95% confidence interval [CI]: 4.5\u20137.6), 8.4 (7.4\u20139.5), 11.1 (8.3\u201314.9), 7.4 (6.0\u20139.2) and 12.0 (9.3\u201315.6) for lithium-, valproate-, olanzapine-, quetiapine- and risperidone-treated groups, respectively. BD patients treated with olanzapine (PS-weighted hazard ratio = 2.07 [95% CI: 1.33\u20133.22]) and risperidone (1.66 [1.08\u20132.55]) had significantly higher all-cause mortality rate than lithium-treated group. Olanzapine was associated with increased risk of natural-cause mortality (3.04 [1.54\u20136.00]) and risperidone was related to elevated risk of unnatural-cause mortality (3.33 [1.62\u20136.86]), relative to lithium. The association between olanzapine and increased natural-cause mortality rate was consistently affirmed in sensitivity analyses. Relationship between risperidone and elevated unnatural-cause mortality became non-significant in sensitivity analyses restricted to low MPR in other mood-stabilizers and monotherapy. Valproate- and lithium-treated groups did not show significant differences in all-, natural- or unnatural-cause mortality risk.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S2045796024000337_sec4d\">\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Our data showed that olanzapine and risperidone were associated with higher mortality risk than lithium, and further supported the clinical guidelines recommending lithium as the first-line mood-stabilizer for BD.
