Clinical implications of admission anemia for electroconvulsive therapy planning in adolescent major depressive disorder: identifying vulnerable subgroups with poorer response.

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
Background: Major depressive disorder (MDD) represents a grave worldwide concern, particularly afflicting the adolescent population. Electroconvulsive therapy (ECT) is widely regarded as a gold-standard intervention for severe forms of MDD, although treatment response varies considerably among individuals. Growing evidence suggests that hematological parameters may influence therapeutic outcomes. This study sought to examine the link between admission anemia and response to ECT treatment. Methods: We analyzed 381 adolescent MDD patients who underwent ECT, comparing demographic and hematological indicators between responders and non-responders. Subgroup analyses were conducted based on gender and depressive subtypes. Results: Among the 381 patients treated with ECT, 272 (71.4%) were classified as responders. Non-responders showed significantly lower baseline hemoglobin levels compared to responders (mean ± SD: 119.0 ± 9.7 vs. 128.7 ± 13.1, p < 0.001). Analysis identified a significant link between hemoglobin levels at admission and the percentage improvement on the HAMD-17 (r = 0.231, p < 0.001). Following confounder adjustment in a binary logistic regression model, anemia at admission was correlated with a lower probability of ECT response [OR (95% CI): 4.051 (2.399-6.840), p < 0.001]. Females and patients with psychotic depression were particularly more susceptible to the impact of admission anemia. Conclusion: Admission anemia is associated with poorer ECT efficacy in adolescent MDD patients. Assessing baseline hemoglobin levels may help optimize ECT treatment planning, especially in female patients and those with psychotic depression.
