Response shift effect on gastrointestinal quality of life index after laparoscopic cholecystectomy.
Article in Quality of life research : an international journal of quality of life aspects of treatment, care and rehabilitation, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled 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.
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
purposeTraditional pre- and post-surgery quality of life assessments are inadequate for assessing change in health-related quality of life (HRQoL) after laparoscopic cholecystectomy (LC). This study examined whether a response shift, a change in the internal standards of a patient, occurs in patients who have received LC.
methodsSelf-administered gastrointestinal quality of life index (GIQLI) was used to evaluate preoperative, postoperative, and retrospective postoperative HRQoL. Response shifts, unadjusted treatment effects, adjusted treatment effects, and their effect sizes were calculated.
resultsIn all GIQLI domains, a significant response shift was indicated by the significantly higher pre-test scores compared to then-test scores (P < 0.05). The effect size of the response shift ranged from 0.19 for the physical impairment domain of the GIQLI to 0.49 for the total GIQLI score. It was observed the treatment effect was greater after adjusting for the presence of response shift.
conclusionPatients who have received LC undergo a response shift that affects their outcome measurement at 6 months postoperative. Response shift is a potentially confounding factor and should be considered when designing clinical studies that employ self-administered HRQoL measures. This evidence of confounding effects warrants further study of response shift at longer intervals after LC, after other health care interventions, and in patients with varying preoperative health status.
