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

aimsNegative symptoms are a core component of schizophrenia, affecting up to 60% of individuals with the disorder. They are categorised into primary negative symptoms (PNS), which are intrinsic to the illness, and secondary negative symptoms, which arise from external factors such as depression or medication side effects. They can also be divided into diminished expression and amotivation/anhedonia subtypes. While inflammation has been implicated in schizophrenia and linked to negative symptoms, little is known about whether inflammatory profiles differ between negative symptom subtypes in individuals at Ultra-High Risk (UHR) for psychosis.

methodsWe conducted a secondary analysis of 147 UHR participants from the Staged Treatment in Early Psychosis (STEP) study to examine whether inflammatory markers (Alpha-2-Macroglobulin, IL-6, CRP, sICAM-1, sVCAM-1, and suPAR) differed across negative symptom subgroups, using multinomial and binomial logistic regression models adjusted for age, sex, smoking, and BMI.

resultsOverall, most inflammatory markers were not significantly associated with negative symptom subgroups. However, higher sICAM-1 levels were asscoiated with lower odds of primary negative symptoms compared with no negative symptoms. Additionally, younger age was associated with increased odds of PNS and amotivation, while smoking was associated with higher odds of secondary negative symptoms compared with no negative symptoms. DISCUSSION: These findings suggest that inflammation may not broadly distinguish negative symptom subtypes at the UHR stage, although sICAM-1 may play a role in early illness processes. Limitations include sample ascertainment, potential misclassification of negative symptoms, and the relatively small number of participants with PNS. Future studies with larger samples and longitudinal designs are needed to clarify whether inflammatory changes contribute to the emergence of specific negative symptom subtypes.
