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

purposeWe aimed to test associations of participant-reported Long COVID symptom interference with life activities with Long COVID symptoms, presence of U09.9 Long COVID diagnosis code, demographics, and clinical factors. In a subgroup, we documented coding related to Long COVID and post-exertional malaise in the electronic medical record (EMR).

methodsUsing a cross-sectional analysis (n = 205) of participant data from a Long COVID survey, we tested associations with Chi-square, Fisher's exact, or Fisher-Freeman-Halton exact statistical tests and Independent Samples T-tests.

resultsParticipants were predominately female (67%) with a mean age of 50.9 years. Participants were White (50.0%), African American (47.5%), and Asian (2.5%); 1.5% reported Hispanic ethnicity. 41% of participants reported high Long COVID symptom interference with life activities. Participants who were older (p=.028), were female (p=.002), were obese (p=.049), had worse general health (p<.001), worse physical health (p<.001), had worse mental health (p<.001), and had U09.9 diagnosis (p<.001) were more likely to experience high symptom interference. Among participants with high symptom interference, there were no significant associations with U09.9 diagnosis code. EMR sub-analysis (n = 100) revealed that among participants that reported high symptom interference (n = 39), 64% (n = 25) had a code related to Long COVID.

conclusionAlthough we found discrepancies between self-reported measures and EMR coding, we did not find evidence of demographic biases in diagnosis among participants with high symptom interference. CLINICAL TRIAL NUMBER: Not applicable.
