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

objectiveTo evaluate whether closed suction drainage (CSD) is associated with early recovery of knee function in patients undergoing total knee arthroplasty (TKA).

methodsBetween January 2015 and September 2015, 80 consecutive patients were prospectively randomized into two groups: a CSD group (40 cases; average age, 66.9 ± 8.6 years; male, 8; female, 32) and a non-CSD group (40 cases; average age, 66.8 ± 10.1 years; male, 9; female, 31). Local inflammation outcomes (assessed by a visual analog scale [VAS], swelling and skin temperature), calculated total blood loss (CBL), hidden blood loss (HBL), blood transfusion requirements and hemoglobin concentrations were recorded. Hospital for Special Surgery (HSS) knee scores, range of motion (ROM), limb swelling, tension vesicles, ecchymosis, time to regaining straight leg raising and duration of hospital stay were documented. All surgeries were performed by the same surgeon and followed up for 3 months.

resultsThe peri-wound skin temperature and knee VAS pain scores were lower in the non-CSD group. Patients in the non-CSD group had significantly better knee ROM (P = 0.028). The time to regaining active straight leg raising was significantly shorter in the non-CSD groupN than in the CSD group (P = 0.014). In addition, patients in the non-CSD group had a shorter length of hospital stay (P = 0.004) than those in the CSD group, indicating earlier recovery of knee function. HBL was significantly less in the CSD group than the non-CSD group (P = 0.006) on postoperative day (POD) 5. However, CBL did not differ significantly between the two groups on POD5. There were no significant differences between two groups in all other assessed variables.

conclusionIn this randomized study, primary TKA without CSD was associated with faster recovery related to less local inflammation and better early knee function. Furthermore, use of a drain had no significant advantage with respect to other outcome measures and may have increased costs. Based on these data, CSD after primary TKA is not routinely indicated.
