Unilateral vs bilateral total knee arthroplasty risk factors increasing morbidity.
Article in The Journal of arthroplasty, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 21 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
Because surgeons are electing to perform simultaneous bilateral total knee arthroplasty (TKA), it is important to identify which patients are at increased risk. We performed a retrospective cohort analysis of 150 patients with unilateral TKA vs 150 patients with simultaneous bilateral TKA. The bilateral group demonstrated a 2.1 times greater mean overall complication rate as well as increased transfusion rates. Patients older than 70 years exhibited significantly higher complication rates. Having a preexisting pulmonary disorder in the bilateral cohort carried nearly a 3-fold risk of complications. Patients with body mass indices greater than 30 displayed a complication rate of 0.97 in the bilateral group as opposed to 0.44 in the control group. Our study demonstrated that age, body mass index, and a preexisting pulmonary disorder resulted in increased complications.
