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

Current models of ocular mechanics do not fully account for potentially large globe translations associated with eye rotation. Such combined motion can be measured using magnetic resonance imaging in axial planes. We imaged orbits of normal volunteers fixating horizontally eccentric targets. These data indicate that the human eye acts as if it rotates eccentrically about a varying point typically anterior to the geometric globe center, but significantly lateral in abduction and medial in adduction. Assumed eccentricity of the ocular rotational center would vary the torque lever arms for the horizontal rectus muscles, with an appreciably smaller relative lever arm for the medial rectus muscle in adduction than would be the case for oculocentric rotation. Such variation in ocular rotational center might alter muscle torque without commensurate change in muscle tension, as appears to happen in convergence.
