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

The aim of this study is To compare robotic-assisted and conventional total knee arthroplasty (TKA) on both short- and long-term outcomes A systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PubMed, Cochrane, Scopus, and Web of Science databases were searched for relevant studies. The studies included were randomised controlled trials directly comparing robotic-assisted versus conventional TKA. The outcomes were pooled as mean difference (MD) or risk ratio (RR), with 95% confidence interval. RevMan software version 5.4 was used for performing the statistical analysis. Nine studies deemed eligible for inclusion. The data showed a significant favouring of robotic-assisted than the conventional TKA in mechanical alignment, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and femoral coronal plane outliers (MD =  - 1.10, 95% CI [- 1.51, - 0.69], p < 0.00001), (MD =  - 1.19, 95% CI [- 2.35, - 0.03], p = 0.04), and (RR = 0.49, 95% CI [0.30, 0.80], p = 0.004), respectively. On the other hand, conventional TKA was better in range of motion-flexion (long-term) than the robotic-assisted one (MD =  - 3.02, 95% CI [- 3.68, - 2.37], p < 0.00001). There were no significant differences between them in knee society score-knee score, knee society score-function score, change in hospital for special surgery (HSS) knee rating scale, and change in range of motion-extension (MD =  - 0.36, 95% CI [- 2.43, 1.70], p = 0.73), (MD =  - 0.34, 95% CI [- 2.36, 1.68], p = 0.74), (MD = 0.78, 95% CI [- 0.84, 2.40], p = 0.34), and (MD = 0.16, 95% [- 1.32, 1.64], p = 0.83), respectively. Robotic-assisted TKA demonstrated better outcomes than conventional TKA in terms of mechanical alignment and WOMAC scores. However, the conventional TKA showed a better range of motion-flexion in the long term. More data are needed to assess long-term outcomes comprehensively.
