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

purposeTo evaluate the combined effect of marker states and a prompt on the reliability and validity of direct utility assessment.

methodsIn a structured interview, 141 prostate cancer (PC) patients provided rating scale (RS) and standard gamble (SG) utilities for their "own health" (RS-/SG-). Following self-completion of comparison instruments (two generic utility and one disease-specific psychometric), they answered a checklist of PC-related items (a prompt to consider self-health) and provided utilities for self-health and mild and severe PC marker states (RS+/SG+). The interview was repeated 5 weeks later, but without comparison instruments. Using Bayesian modeling, we computed and compared correlation coefficients to assess RS and SG test-retest reliability and validity and the effects of the prompt and marker states.

resultsRS and SG had acceptable test-retest reliability (intraclass correlation coefficients = 0.57-0.63). The prompt and marker states decreased the reliability of the RS by 0.01 (from 0.58 to 0.57) but increased the reliability of the SG by 0.05 (from 0.58 to 0.63). The probability that the reliability of the SG+ was greater than that of the SG- was very high (0.96). Correlations with comparison instruments were higher by 0.01-0.06 for RS+ vs RS-, and higher by 0.03-0.06 for SG+ vs SG-. The probabilities that the prompt and marker states improved validity ranged from 0.55 to 0.74 (RS), and from 0.61 to 0.70 (SG).

conclusionsA self-health description prompt and marker states modestly improved the reliability and validity of direct utility elicitation.
