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
backgroundBipolar disorder is associated with a high prevalence of suicidal ideation, and comorbid anxiety may further increase suicide risk. The psychological mechanisms linking anxiety to suicidal ideation, especially the roles of social support and self-esteem, remain unclear. This study constructed a chain mediation model to examine how anxiety, social support and self-esteem relate to suicidal ideation in patients with bipolar disorder.
methodsFrom March 2022 to May 2023, 450 inpatients with bipolar disorder were recruited from six hospitals in Anhui Province. Standardised scales assessed anxiety, social support, self-esteem and suicidal ideation. Pearson correlation examined associations between variables, binary logistic regression identified factors associated with suicidal ideation, and Hayes' PROCESS macro tested the chain mediation model.
resultsLogistic regression showed that higher anxiety increased the odds of suicidal ideation, whereas higher social support and self-esteem reduced the odds. Suicidal ideation was positively correlated with anxiety and negatively correlated with social support and self-esteem, and mediation analysis demonstrated a significant direct effect of anxiety and significant independent and chain mediating effects of social support and self-esteem (all p < 0.001).
conclusionsAnxiety is related to suicidal ideation in patients with bipolar disorder both directly and indirectly through reduced social support and self-esteem. The indirect pathway via self-esteem showed the largest effect, underscoring the need to enhance social support and self-esteem in suicide prevention for this population.
