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

backgroundObesity has been linked to higher rates of postoperative complications, delayed wound healing, reoperation, and re-revision rate following revision total knee arthroplasty (RTKA). This study examined the impact of obesity across various weight classes on RTKA outcomes: healthy weight (body mass index [BMI] < 25); overweight (BMI 25 to 29.9); class I obesity (BMI 30 to 34.9); class II obesity (BMI 35 to 39.9); class III, type 1 obesity (BMI 40 to 44.9); class III, type 2 obesity (BMI 45 to 49.9); and severe class III obesity (BMI ≥ 50).

methodsWe retrospectively reviewed an institutional database of patients who underwent RTKA over a period of 15 years. Data on demographics, re-revision rate, RTKA survivorship, postoperative complications, mortality rate, readmissions, 90-day costs, and functional outcomes were collected. Comparisons among BMI groups were made with Kruskal-Wallis tests for non-normal data and χ

resultsA total of 550 patients were included in the study, categorized into 7 BMI groups. The overall re-revision rate was 17%, with the BMI 45 to 49.9 (hazard ratio [HR] 2.4,

conclusionA BMI of 45 to 49.9 and ≥ 50 are risk factors for re-revision, postoperative infection, and readmission rates and increase the 90-day costs associated with RTKA.
