Clinical Outcome Comparison between Staged -Bilateral Versus Simultaneous Bilateral Total Knee Replacements.
Article in The archives of bone and joint surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
backgroundThis retrospective study aimed to compare the clinical outcomes of patients with staged and simultaneous bilateral total knee arthroplasty (TKA).
methodsThe present study included 100 patients with a mean age of 62±3.72 years from 2014 to 2017. Among them, 51 and 49 patients underwent simultaneous and staged bilateral TKA, respectively. The two groups were compared regarding the range of motion (ROM), Oxford Knee Score (OKS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) improvement, and Medical Outcomes Study 36-item Short-Form Health Survey (SF-36) scores. The mean follow-up duration was 24 months (range: 12-36 months).
resultsAccording to the results obtained from the SF-36 questionnaire (possessing eight different factors of quality of life), there was no significant difference between the two groups. Furthermore, the OKSs were 39.98±1.52 and 38.68±2.55 in the simultaneous and staged groups, respectively. Moreover, the WOMAC improvement scores were obtained at 84.15±2.2 and 83.26±2.6 in the simultaneous and staged groups, respectively. The final knee ROM was acceptable without a significant difference between the two groups.
conclusionSubstantial controversy about the complications, functional, and clinical outcomes has negatively affected the decision of the surgeons on conducting bilateral sequential TKA. This clinical assessment revealed that all determinants, including OKS, WOMAC, SF-36, ROM, postoperative bleeding, and hospitalization duration exhibited almost the same improvement in both groups. According to this study, no statistically significant difference exists in both procedures.
