1 · What the graph read from 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.

2 · The registry

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

BACKGROUND/

objectivesLong COVID is a long-term legacy of the global pandemic. This study aimed to illuminate how Long COVID impacts individuals, and how response-shift effects influence Long COVID's impact. Methodologically, it expands the application of longitudinal statistical methods to test a more dynamic investigation of psychosocial factors in health over time.

methodsThis quasi-experimental longitudinal cohort study collected data up to four times over 3 years of the COVID pandemic (May 2020 to April 2023). This study focused on 1151 participants divided into four Long-COVID Symptom Burden groups (Never Had COVID; Low, Medium, and High Long-COVID Symptom Burden). It examined COVID-specific outcomes: General Hardship, Healthcare Hardship, Worry, and Social Support. The Quality of Life Appraisal Profile

resultsNotable response-shift effects were revealed on all four COVID-specific outcomes, reflecting both direct and moderated response-shift effects. The experience of COVID-specific adversity was related to various appraisal processes but the nature of the relationship often varied by Long-COVID symptom burden. The appraisal processes that were most salient included patterns of emphasis related to getting used to and handling demands or recent changes, problem-solving goals, and comparing oneself to similar others. Individuals in the high Long-COVID Symptom-Burden Group were particularly highlighted in response-shift effects. The broad conclusions of both raw and multiplicity-adjusted results were similar. That is, there were notable reprioritization and reconceptualization response-shift effects for all outcomes, and notable but fewer recalibration response-shift effects.

conclusionsResponse-shift effects, measured via the direct assessment of cognitive-appraisal processes, were prominent in dealing with the COVID pandemic. The present study documented that COVID-specific adversity can be attenuated or exacerbated depending on individuals' patterns of emphasis, goals, and standards of comparison. The study's utilization of data collected at four time points over 3 years of the global pandemic provided a more comprehensive and far-reaching evaluation of response shift than earlier work. The theory-driven analytic methodology developed in the present work facilitated a more nuanced description of direct and moderated response-shift effects.
