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

LEARNING

objectiveAfter participating in this activity, learners should be better able to:• Evaluate the relationship between negative symptoms and functioning in youth at clinical high risk for psychosis.

aimYouth at CHR for psychosis often demonstrate significant negative symptoms and poor functioning, though the magnitude and direction of the relationship between the two remains unknown. The objective of this systematic review is to summarize the relationship between negative symptoms and functioning in CHR samples.

methodElectronic databases CINAHL, EBM, Embase, MEDLINE, and PsycINFO were searched from inception. Studies were selected if they included any study that reported a relationship between negative symptoms and functioning in youth at clinical high risk (CHR). The correlation coefficient r was converted to Cohen's d, and all random-effects meta-analyses were performed using the transformed values.

resultsForty-one studies met the inclusion criteria, including a total of 4574 individuals at CHR for psychosis. Negative symptom total scores were significantly associated with poorer global functioning (d, -1.40; 95% CI, -1.82 to -0.98; I = 79.4%; p < .001 [9 studies, n = 782]), social functioning (d, -1.10; 95% CI, -1.27 to -0.93; I = 10.40%; p < .001 [12 studies, n = 811]), and role functioning (d, -0.96; 95% CI, -1.17 to -0.76; I = 41.1%; p < .001 [9 studies, n = 881]). In addition, negative symptoms were consistently associated with poor premorbid functioning. When examining negative symptom domains, avolition, anhedonia, and blunted affect were each significantly and independently associated with poorer social functioning and role functioning. In terms of prediction models, negative symptoms contributed to the prediction of lower functioning across multiple studies.

conclusionThis meta-analysis demonstrates a strong relationship between negative symptoms and functioning in youth at clinical high risk for psychosis.
