Can bariatric surgery delay the need for knee replacement in morbidly obese osteoarthritis patients.
Article in Journal of minimal access surgery. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled 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.
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
objectiveThe objective of the study was to find the weight reduction pattern and its outcome on knee pain and function in osteoarthritis (OA) morbidly obese patients' post-bariatric surgery with dietary and exercise changes. METHODOLOGY: Thirty morbidly obese (body mass index [BMI] >40 kg/m2) OA patients gave consent for bariatric surgery. Despite wearisome lifestyle modifications for weight loss and knee pain, satisfactory results were not retrieved. We took consent from all the patients predetermined for knee replacement in future because of pain and disability as recommended by knee replacement surgeon. The dietary and exercise protocol was standardised for all patients for bariatrics. Data for weight loss, change in BMI and Western Ontario and McMaster Universities Arthritis Index score consisting of pain, stiffness and activities of daily livings (ADLs) scores were documented at baseline, 3 months and 6 months post-bariatric surgery.
resultsThe male-to-female ratio was 1:2. Mean age of the patients was 49.8 ± 8.6 years. Significant changes in pain (P < 0.001), stiffness (P < 0.001) and ADLs (P < 0.001) were found postoperatively at 3 and 6 months. Positive correlation of percentage change of BMI was seen with percentage change in pain (r = 0.479, P = 0.007) and ADLs (r = 0.414, P = 0.023) after 6 months of bariatric surgery. Most of the patients were inclined to delay the knee replacement further by the end of 6 months post-bariatric surgery.
conclusionBariatric surgery when combined with dietary and exercise changes gave significant results in terms of weight loss, knee pain and function. It is an approach that tackles both obesity and OA. It is a major step forward in stemming the global epidemic of these two interlinked conditions.
