Effects of preoperative personal education on shoulder function and lymphedema in patients with breast cancer: A consort.

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
backgroundTo compare the incidence and severity of ipsilateral shoulder dysfunction and lymphedema of 2 groups of patients needing to undergo unilateral breast cancer surgery, one of which had only received printed education materials and the other group which had received educational materials plus preoperative education.
methodsWe selected 61 patients who had been diagnosed with unilateral breast cancer and planned to undergo surgery. Before surgery, patients were randomly assigned, either to a control group that only received printed education materials about exercise for shoulder pain relief and lymphatic edema prevention following breast cancer surgery, or to an experimental group that received the printed education material with personal education. Participants were evaluated at 1, 3, 6, and 12 months after the surgery. To evaluate the impairment of shoulder function, we measured the passive shoulder range of motion (ROM), the degree of pain as visual analog scale (VAS), the short version of the disability of arm, shoulder, and hand (short DASH) scores, and the shoulder pain and disability index (SPADI). We checked arm circumferences to evaluate lymphedema.
resultsThere was no significant difference in demographic or clinical variables between the control and experimental groups. The experimental group showed significantly less limitation in abduction (P = .042) and forward flexion (P = .039) in the 6 months following surgery. Change in the VAS, short DASH, and SPADI scores were 1.633 (P < .001), 2.167 (P < .001), and 4.1 (P = .003) at 1 month following surgery, respectively. These then decreased with time. These changes started before shoulder ROM and arm circumference changes had occurred, which had started 3 months following surgery.
conclusionsPreoperative education might be helpful for the prevention of a shoulder ROM limitation, and we need to focus on pain and disability in patients immediately following breast cancer surgery, and then on ROM and lymphedema.
