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

backgroundTotal knee arthroplasty (TKA) is the most common treatment for end-stage knee osteoarthritis and continuous femoral nerve block (CFNB) has become the gold standard for analgesia. But the lack of knowledge about CFNB and patient-controlled analgesia (PCA) often leads to inappropriate dose of medications and increased workload for ward nurses.

methodsAfter retrospectively registering to http://www.chictr.org.cn (ChiCTR1800018957), 60 patients undergoing unilateral TKA were randomly divided into groups A and B (n = 30 each). Patients in group B and their families received a nurse-led preoperative visit the day before surgery focusing on PCA educational pamphlets for postoperative pain management. Before returning to the ward, patients and their families in both groups received face-to-face PCA pump operation training. The usual postoperative follow-up was performed by nurse anesthetists for 2 consecutive days. Visual Analogue Scale (VAS) scores at rest and during movement, knowledge of the PCA evaluated by a ten-question questionnaire, knee flexion angles, and the number of PCA-related nurse calls were recorded.

resultsThe VAS scores at rest and during movement of the patients in group B were both significantly lower than in group A on postoperative days 1 and 2. The questionnaire scores of the patients in group B were much higher than those in group A on postoperative day 1, but not on day 2. Patients in the 2 groups had similar knee flexion on postoperative days 1 and 2. Patients in group B asked for assistance from the ward nurses with the PCA fewer times than those in group A, and the ward nurses were more satisfied with the analgesic protocol in group B.

conclusionsEnhanced preoperative education for CFNB with PCA can provide patients with a better grasp of postoperative pain management, improve the postoperative analgesic effect after TKA, and reduce the PCA-related workload for ward nurses.
