Outcomes of endovascular treatments of aneurysms: observer variability and implications for interpreting case series and planning randomized trials.

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
background and purposeAngiographic results are commonly used as a surrogate marker of success of coiling of intracranial aneurysms. Inter- and intraobserver agreement in judging angiographic results remain poorly characterized. Our goal was to offer such an evaluation of a grading scale commonly used to evaluate results of endovascular treatment of aneurysms. MATERIALS AND
methodsA portfolio of 90 angiographic images from 45 patients selected from the core lab data base of a randomized trial was sent to 12 observers on 2 occasions more than 3 months apart. The variability of a 3-value grading scale used to score angiographic results and of a final judgment regarding the presence of a recurrence was studied using κ statistics.
resultsTen participants responded once and 6 responded twice. Agreement was poor to moderate (κ = 0.28-0.5) for senior and junior observers judging angiographic results immediately or 12-18 months after treatment. Agreement reached a reassuring "substantial" (κ = 0.62) level, with a dichotomous presence-absence of a major recurrence, and intraobserver agreement was better in experienced core lab assessors.
conclusionsThere is an important variability in the assessment of angiographic outcomes of endovascular treatments, rendering comparisons between publications risky, if not invalid. A simple dichotomous judgment can be used as a surrogate outcome in randomized trials designed to assess the value of new endovascular devices.
