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.

2 · The registry

The trial behind it

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.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Objective: Postoperative neurocognitive disorders impact 40 to 50% of patients after cardiac surgery. In older adults, walking more than 6500 steps per day is associated with cognitive benefits. The purpose of this study was to determine if walking 6500 steps or more per day before surgery was associated with less postoperative neurocognitive disorder. Methods: This single-center, observational, pilot study enrolled patients aged 60 years or more undergoing elective cardiac surgery. Daily step counts were recorded continuously for at least 5 full days before surgery and for 90 days after surgery. Montreal Cognitive Assessment was administered (1) at enrollment, (2) at discharge, (3) on postoperative day 30, and (4) on postoperative day 90. Patients were stratified into low steps (<6500 steps/day) or high steps (≥6500 steps/day) based on their preoperative average daily step count. Postoperative cognitive decline was defined as 1 or more SD decline in Montreal Cognitive Assessment score from baseline. Results: A total of 44 patients were enrolled, and 39 patients completed the study. Patients' average age was 67 years, 41.7% were female, and 61.5% were in the low steps cohort. Median preoperative step counts in patients with low steps versus high steps were 5002 versus 9140 ( Conclusions: Walking 6500 steps or more per day before surgery predicts better postoperative cognitive performance.
