A Multivariate Analysis on the Effect of No Closed Suction Drain on the Length of Hospital Stay in Total Knee Arthroplasty.
Article in Knee surgery & related research, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03954860 (Effect of no Drainage Tube on Blood Loss and Recovery After High Tibial Osteotomy), which is not on this map. Cited by 8 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.

Abstract
purposeDespite the long history of drain use in total knee arthroplasty (TKA), no drain has been gaining popularity. The purpose of this study was to investigate whether drainage is related to the length of hospital stay. MATERIALS AND
methodsA total of 166 consecutive unilateral TKAs performed on 135 patients with osteoarthritis were retrospectively reviewed. Closed suction drainage was used in 111 cases (67%). Length of hospital stay after surgery was recorded, and a multivariate linear regression analysis was performed to evaluate various variables (patient factors, surgical factors, and post-surgical factors) and to investigate whether drainage was an independent variable.
resultsHospital stay was shorter in no drain cases (21.7±4.8 days) than in drain cases (24.2±3.7 days, p<0.001). The multivariate analysis showed that older age (β=0.12, p=0.02), drain use (β=2.81, p=0.03), and occurrence of comorbidity (β=1.46, p=0.04) were the independent variables associated with the extended hospital stay. There was no difference in comorbidity between drain cases (39.6%) and no drain cases (27.2%, p=0.13).
conclusionsThe drain use, age, and occurrence of comorbidity were related to the length of hospital stay. TKA without drain is an effective procedure both medically and economically.
