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

Aims: Our aim was to investigate the psychometric properties of the health assessment instrument EQ-5D-5L in OHCA survivors. Methods: We included survivors from the Targeted Hypothermia versus Targeted Normothermia after OHCA (TTM2) trial, who completed EQ-5D-5L at 6 months. Confirmatory factor analysis was used to evaluate the hypothesised unidimensional latent structure of EQ level sum score (EQ LSS), summarizing scores across Results: 783 of 939 (84%) eligible survivors were included. Confirmatory factor analysis showed good model fit and strong factor loadings for all dimensions (0.61-0.90). We observed a significant but negligible effect of age on Mobility (β = 0.29, p < 0.001, ΔR Conclusion: The psychometric properties of EQ LSS support its use to measure health status in OHCA research. The strong association between health and functional dependency indicate robust and comparable construct validity for EQ LSS, EQ value, and EQ VAS in this sample.
