    Summary
    From baseline to week 12, compared with placebo, linaclotide significantly reduced presenteeism by 5.2%, overall work productivity loss by 6.1%, and daily activity impairment by 4.7% (all P <.01) and led to a numerically greater decrease in absenteeism.

    Summary · context
    Of the 1602 patients with IBS-C who were randomized in the 2 clinical trials, 1555 (97.1%) completed a baseline and at least 1 postbaseline WPAI:IBS-C assessment and were included in the analysis cohort; 1148 (71.7%) of these patients were employed.
