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
purposeTo investigate the presence and clinical impact of response shift (RS) on longitudinal patient-reported outcome (PRO) assessment among older people living with HIV/AIDS (PLWHA), and to evaluate how not accounting for RS may affect the interpretation of changes in PRO at both domain and item levels.
methodsA two-wave longitudinal survey with a 3-month interval was conducted among older PLWHA (baseline n = 1245; follow-up rate 84.90%) using the PROHIV-OLD instrument. Domain-level RS-including reconceptualization, recalibration, and reprioritization-was examined using Oort's structural equation modeling (SEM) approach. Item-level recalibration was further assessed within the Mental Status domain using the updated ROSALI-Rasch measurement theory (RMT) algorithm, incorporating clinical subgroups defined by diagnostic duration, disease stage, and HIV-1 RNA status.
resultsAt the domain level, a medium uniform recalibration was detected for Physical Symptoms (Est. = 0.65, Δχ
conclusionRS substantially informs longitudinal PRO assessment in older PLWHA. Accounting for RS effects can improve the interpretation of changes in PROs and support more patient-centered clinical evaluation in aging HIV populations.
