1 · What the graph read from it

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.

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Abstract

aimsCognitive decline is common after cardiac surgery and is associated with poor postoperative outcomes. The aim of this study was to evaluate the feasibility and acceptability of a home-based computerised cognitive training programme to improve POCD following cardiac surgery; this study was not designed to assess the efficacy of the intervention.

methodsThis single-arm, non-blinded, feasibility and acceptability study included patients ≥ 18 years undergoing first-time elective cardiac surgery using standard extracorporeal circulation. Participants were required to complete an 8-week computerised cognitive training (CCT) programme (20 min/day; 5 days/week), commencing 1 week after surgery. The Montreal Cognitive Assessment (MoCA) was administered preoperatively and after programme completion. Feasibility outcomes included recruitment and retention rates and programme adherence. Acceptability was assessed by the Theoretical Framework of Acceptability Questionnaire (TFA-Q).

resultsTwenty-nine participants were recruited: 7 (24%) were female and 20 (69%) were White British. Study recruitment was deemed to be feasible (61% of eligible patients) and the CCT was acceptable to 94% of participants who completed the TFA-Q (n = 16), noting that this does not reflect the full recruited cohort. Intervention adherence (n = 9, 31%) and study retention (n = 17, 59%) were limited.

conclusionsThe findings of this feasibility study suggest that home-based CCT is deliverable and acceptable to patients following cardiac surgery, though strategies to improve retention and adherence will need to be strengthened before progression to an efficacy study.
