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

objectiveIllness duration has been examined as a predictor of anorexia nervosa (AN) outcomes to mixed results, yet is frequently used to make treatment and prognosis decisions. More specific metrics, such as prior illness course (e.g., continuous vs. intermittent symptoms) and symptom-specific duration or course, may more effectively predict concurrent and longitudinal outcomes.

methodAdults with acute or weight-restored AN (N = 75) completed a measure assessing duration and course (e.g., continuous, intermittent) of their eating disorder in general and of specific symptoms (low weight, restrictive eating, weight/shape preoccupation). Hierarchical linear regressions predicted the severity of each symptom (BMI, restrictive eating, shape concern, weight concern) at baseline and one-year follow-up from covariates (Step 1), general illness duration and course (Step 2), and symptom-specific duration and course (Step 3).

resultsCross-sectionally, symptom-specific predictors improved model fit for all outcomes (ps = < 0.001-0.043). A more continuous course of restrictive eating was associated with more frequent baseline restrictive eating (p = 0.002) and longer duration (p = 0.009) and a more continuous course (p < 0.001) of weight/shape preoccupation was associated with higher baseline shape concern. General illness duration and course did not predict symptom severity after accounting for symptom-specific factors. Longitudinally, no measure of illness or symptom duration or course predicted follow-up symptom severity.

conclusionsCourses of specific symptoms may be more meaningful symptom severity markers in AN than general illness duration or course, particularly for restriction and shape concern. Findings highlight the clinical utility of assessing symptom-specific chronicity and of interrupting eating disorder symptoms in treatment, given the impact of continuous symptom expression.
