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
backgroundElderly hip fracture patients (patients aged ≥ 60 years) require prolonged rehabilitation after surgery and are care-dependent. Patients’ care dependence was strongly associated with the recovery of health-related quality of life. This study aimed to explore the trajectory and influencing factors of care dependence among elderly patients 14 days after total hip arthroplasty (THA) during their hospital stay.
methodsUsing the convenience sampling methodology, 210 elderly patients who underwent THA in three tertiary comprehensive hospitals in Jingzhou City and Yichang City from February to August 2023 were selected and recruited as the research subjects. The demographic and disease data questionnaire and the Orthopedic Social Support Scale were used to collect baseline information about the patients, and the Care Dependency Scale was used to follow up with the older patients at 24 h postoperatively (T1), on postoperative day 7(T2), and on postoperative day 14 (T3) for longitudinal assessment. The Latent Growth Mixture Model (LGMM) was used to describe the overall trend of care dependence, and a multivariate logistic regression model was adopted to analyze the effects of relevant factors on the trajectory of change in care dependence among elderly patients.
resultsLGMM analysis revealed three distinct trajectories: a high dependency group (55.24%), a gradual decline group (37.62%), and a rapid decline group (7.14%). Compared to the high dependency group, membership in the gradual decline group was significantly associated with young-old, no complications, family members as the primary caregiver, and better social support (all p < 0.05). Lower education levels (both journal school and primary school or below, vs. high school or above) remained a negative predictor. For the rapid decline group, younger age and higher educational attainment (indicated by the negative effect of primary school or below education) were the significant predictors.
conclusionsEarly post-THA care dependency follows heterogeneous trajectories in older patients, primarily driven by two mechanistic pathways: a compensatory pathway (where external support facilitates gradual recovery in vulnerable individuals) and an autonomous pathway (where intrinsic capacity enables rapid recovery). Early screening for age, education, and support systems allows for risk stratification and personalized interventions to improve recovery outcomes. CLINICAL TRIAL NUMBER: Not applicable.
