What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract

BACKGROUND &

aimsPatients with cirrhosis and minimal hepatic encephalopathy (MHE) have driving difficulties but the effects of therapy on driving performance is unclear. We evaluated whether performance on a driving simulator improves in patients with MHE after treatment with rifaximin.

methodsPatients with MHE who were current drivers were randomly assigned to placebo or rifaximin groups and followed up for 8 weeks (n = 42). Patients underwent driving simulation (driving and navigation tasks) at the start (baseline) and end of the study. We evaluated patients' cognitive abilities, quality of life (using the Sickness Impact Profile), serum levels of ammonia, levels of inflammatory cytokines, and model for end-stage-liver disease scores. The primary outcome was the percentage of patients who improved in driving performance, calculated as follows: total driving errors = speeding + illegal turns + collisions.

resultsOver the 8-week study period, patients given rifaximin made significantly greater improvements than those given placebo in avoiding total driving errors (76% vs 31%; P = .013), speeding (81% vs 33%; P = .005), and illegal turns (62% vs 19%; P = .01). Of patients given rifaximin, 91% improved their cognitive performance, compared with 61% of patients given placebo (P = .01); they also made improvements in the psychosocial dimension of the Sickness Impact Profile compared with the placebo group (P = .04). Adherence to the assigned drug averaged 92%. Neither group had changes in ammonia levels or model for end-stage-liver disease scores, but patients in the rifaximin group had increased levels of the anti-inflammatory cytokine interleukin-10.

conclusionsPatients with MHE significantly improve driving simulator performance after treatment with rifaximin, compared with placebo.
