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
introductionThe objective of the current study was to evaluate the reoperation rate among patients undergoing cemented total knee arthroplasty (TKA) with or without an intraoperative tourniquet. MATERIALS AND
methodsA retrospective cohort study of consecutive patients who received a primary, cemented TKA at a high volume academic orthopaedic center. Eligible patients underwent primary, cemented TKA either with or without the use of a tourniquet throughout the entirety of the care. The causes and timing of reoperations were recorded. Survivorship analysis was conducted using Kaplan-Meier curves. Cox proportional hazards models were utilized to evaluate independent predictors of reoperation.
resultsThere were 2276 (58%) cases in which a tourniquet was used and 1663 (42%) cases with no tourniquet use. Mean time from the primary TKA was 14.7 years. The cumulative survival at final follow-up for the no tourniquet group and tourniquet group were 92.2% and 96.5%, respectively. Only younger age was an independent predictor of both all cause revision and aseptic loosening.
conclusionsAdjusting for confounders, the presence of a tourniquet did not affect the rates of long-term all-cause revision rates or aseptic loosening. Younger patients have a higher risk of all-cause reoperation and reoperation due to aseptic loosening. LEVEL OF EVIDENCE: Level III.
