Differences in peri-operative serum inflammatory markers between normoponderal and obese patients undergoing large joint replacement for osteoarthritis-a descriptive study.
Article in International orthopaedics, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThe occurrence, evolution and treatment outcome of osteoarthritis are influenced by a series of factors, including obesity. Assessing how chronic inflammation present in obesity changes the values of peri-operative biological tests could facilitate a clearer interpretation of laboratory examinations for the proper management of possible complications.
methodsThis descriptive study compared biological and clinical factors during the peri-operative period in patients undergoing total hip/knee replacement, in order to identify the special characteristics of the inflammatory status in obese compared to normal weight patients. In the two groups (71 normoponderal, 74 obese), serum levels of fibrinogen, high-sensitivity C-reactive protein (hsCRP), tumour necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) were determined 24 hours pre- and post-operatively.
resultsOur results found significant post-operative increases in serum levels of IL-6 and hsCRP in both groups (p = 0.0001), with inter-group differences in pre-operative hsCRP (p = 0.02) and post-operative IL-6 levels (p = 0.013). Interestingly, TNF-alpha levels were much higher in the obese pre-operatively than post-operatively (p = 0.002) and higher than the normoponderals (p = 0.003), decreasing to levels similar to those of the normal weight patients on day two.
conclusionsBecause of its important clinical implications, an appropriate comprehension of the peri-operative changes in a patient's inflammatory status has the potential to influence therapeutic attitude. We failed to observe any significant post-operative differences in the mean values of the markers assessed, except those of IL-6, implying that serum levels of fibrinogen, hsCRP and TNF-alpha within 24 hours after large joint replacements are not influenced by the patient's ponderal status.
