Weight patterns before and after total joint arthroplasty and characteristics associated with weight change.
Article in The Permanente journal, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06440863 (The Effect of Changes in Body Mass Index After Total Knee and Hip Arthroplasty on Patient Functional Scores), which is not on this map. Cited by 12 papers.
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.
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.

Abstract
contextAlthough prevalence of obesity and incidence of total joint arthroplasty (TJA) have dramatically increased over the last two decades in the U.S., little is known of the preoperative and postoperative weight patterns of patients undergoing TJA.
objectiveTo describe the preoperative and postoperative weight patterns of patients undergoing TJA and evaluate characteristics associated with these patterns.
designRetrospective cohort study. A cohort of patients undergoing total hip arthroplasty (THA) or total knee arthroplasty (TKA) between January 1, 2008, and December 31, 2010, was identified. Using weight obtained at patient encounters, patients were categorized into gainers (increased weight by 5%), losers (decreased weight by 5%), or remained the same (changed < 5%) for the preoperative and postoperative periods. Patients were characterized by sex, age, and race.
main outcome measuresWeight change before and after TJA.
resultsOf 30,632 patients with TJA identified, 34.5% underwent THA and 65.5% had TKA. Most patients remained the same weight during the year before (THA, 71.5%; TKA, 75.7%) and after the procedure (64.0% and 68.5%, respectively). Before and after THA, men were less likely to lose or gain weight than were women. Older patients were less likely to gain weight. Among patients undergoing TKA, men were less likely to lose weight preoperatively or postoperatively, or gain weight postoperatively, and older patients were less likely to gain weight before or after arthroplasty. Some racial associations with weight patterns were observed.
conclusionsSpecific groups are more susceptible to weight change and could benefit from weight management interventions.
