Predictors of survey non-response two years after hip arthroscopy: Results from an institutional prospective registry.
Article in Journal of orthopaedics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Purpose: Survey-based studies are inherently subject to non-response bias. A comprehensive understanding of the factors contributing to non-response is important for minimizing attrition bias and ensuring generalizability of results. The purpose of this study was to determine the preoperative factors associated with survey non-response 2 years after hip arthroscopy. Methods: Patients undergoing hip arthroscopy at a single center between October 2015 and March 2020 were approached for enrollment in a prospective registry. Patients were emailed an electronic survey at baseline and at 1 and 2 years postoperatively. The primary outcome was response to the 2-year postoperative survey. Patients who failed to complete any part of the 2-year postoperative survey after a series of standardized email, text message, and phone call reminders were considered non-responders. Baseline sociodemographics and patient-reported outcomes (PROs) were compared between the groups using Pearson Chi-Squared or Wilcoxon Rank-Sum tests. Logistic regression was used to identify predictors of non-response. Results: Ninty-nine patients were enrolled and completed the baseline survey. There were 25 non-responders (25 %) at 2 years. Non-responders demonstrated a higher proportion of patients who were male, identified as non-white, and did not respond to the 1-year postoperative survey. There were no differences in baseline PROs between responders and non-responders. When controlling for age and sex, patients who did not identify as white (OR = 4.3, 95 % CI [1.3, 14.4]) and patients who did not respond to the 1-year postoperative survey (OR = 4.5, 95 % CI [1.5, 13.8]) were more likely to be non-responders at 2 years. Conclusion: Not responding to 1 year postoperative survey and non-white race are independent predictors of non-response at 2 years after hip arthroscopy. Baseline PROs do not differ between responders and non-responders.
