A Cross-Sectional Analysis of the Readability of Online Information Regarding Hip Osteoarthritis
Bibliographic record
Abstract
Introduction Osteoarthritis (OA) is an age-related degenerative joint disease. There is a 25% risk of symptomatic hip OA in patients who live up to 85 years of age. It can impair a person's daily activities and increase their reliance on healthcare services. It is primarily managed with education, weight loss and exercise, supplemented with pharmacological interventions. Poor health literacy is associated with negative treatment outcomes and patient dissatisfaction. A literature search found there are no previously published studies examining the readability of online information about hip OA. Objectives To assess the readability of healthcare websites regarding hip OA. Methods The terms "hip pain", "hip osteoarthritis", "hip arthritis", and "hip OA" were searched on Google and Bing. Of 240 websites initially considered, 74 unique websites underwent evaluation using the WebFX online readability software (WebFX®, Harrisburg, USA). Readability was determined using the Flesch Reading Ease Score (FRES), Flesch-Kincaid Reading Grade Level (FKGL), Gunning Fog Index (GFI), Simple Measure of Gobbledygook (SMOG), Coleman-Liau Index (CLI), and Automated Readability Index (ARI). In line with recommended guidelines and previous studies, FRES >65 or a grade level score of sixth grade and under was considered acceptable. Results The average FRES was 56.74±8.18 (range 29.5-79.4). Only nine (12.16%) websites had a FRES score >65. The average FKGL score was 7.62±1.69 (range 4.2-12.9). Only seven (9.46%) websites were written at or below a sixth-grade level according to the FKGL score. The average GFI score was 9.20±2.09 (range 5.6-16.5). Only one (1.35%) website was written at or below a sixth-grade level according to the GFI score. The average SMOG score was 7.29±1.41 (range 5.4-12.0). Only eight (10.81%) websites were written at or below a sixth-grade level according to the SMOG score. The average CLI score was 13.86±1.75 (range 9.6-19.7). All 36 websites were written above a sixth-grade level according to the CLI score. The average ARI score was 6.91±2.06 (range 3.1-14.0). Twenty-eight (37.84%) websites were written at or below a sixth-grade level according to the ARI score. One-sample t-tests showed that FRES (p<0.001, CI -10.2 to -6.37), FKGL (p<0.001, CI 1.23 to 2.01), GFI (p<0.001, CI 2.72 to 3.69), SMOG (p<0.001, CI 0.97 to 1.62), CLI (p<0.001, CI 7.46 to 8.27), and ARI (p<0.001, CI 0.43 to 1.39) scores were significantly different from the accepted standard. One-way analysis of variance (ANOVA) testing of FRES scores (p=0.009) and CLI scores (p=0.009) showed a significant difference between categories. Post hoc testing showed a significant difference between academic and non-profit categories for FRES scores (p=0.010, CI -15.17 to -1.47) and CLI scores (p=0.008, CI 0.35 to 3.29). Conclusions Most websites regarding hip OA are written above recommended reading levels, hence exceeding the comprehension levels of the average patient. Readability of these resources must be improved to improve patient access to online healthcare information which can lead to improved patient understanding of their own condition and treatment outcomes.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
