Construct validity and responsiveness of the Duke Activity Status Index (DASI) as a measure of recovery after colorectal surgery.
Article in Surgical endoscopy, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundReturning to preoperative levels of physical function is highly valued by patients recovering from surgery. The Duke Activity Status Index (DASI, a 12-item questionnaire) may be a simple yet robust tool to assess postoperative recovery of functional capacity. This study assessed construct validity and responsiveness of the DASI as a measure of recovery after colorectal surgery.
methodsData from a trial on early mobilization after colorectal surgery were analyzed. Patients completed the DASI questionnaire preoperatively and at postoperative weeks (POW) 2 and 4. Construct validity was assessed by testing the primary a priori hypotheses that postoperative DASI scores (1) are higher in patients without vs with postoperative complications and (2) correlate with six-minute walk test distance (6MWD). Exploratory analyses assessed the association between DASI scores and (1) preoperative physical status [higher (ASA ≤ 2) vs lower (ASA > 2)], (2) stoma creation (no stoma vs stoma), (3) age [younger (≤ 75 years) vs older (> 75 years)], (4) time to readiness for discharge [shorter (≤ 4 days) vs longer (> 4 days)], and (5) surgical approach (laparoscopic vs open). Responsiveness was assessed by testing a priori hypotheses that DASI scores are higher (1) preoperatively vs at POW2 and (2) at POW4 vs POW2. Mean differences in DASI scores were obtained using linear regression. The association between DASI and 6MWD was assessed via Pearson correlation.
resultsWe analyzed data from 100 patients undergoing colorectal surgery (mean age 65; 57% male; 81% laparoscopic). Mean DASI scores were 47.9 ± 12.1 preoperatively, 22.4 ± 12.7 at POW2, and 33.2 ± 15.7 at POW4. The data supported our two primary construct validity hypotheses, as well as 3/5 exploratory hypotheses. Both responsiveness hypotheses were supported.
conclusionsOur findings support that the DASI questionnaire can be a useful tool to assess postoperative recovery of functional capacity in research and clinical practice.
