Clinicians' experience on the effectiveness of pharmacotherapy in patients with first-episode depression: a randomized controlled trial based on pharmacogenomics.
Article in Frontiers in pharmacology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Due to differences in drug efficacy, the risk of adverse reactions, and individual differences between patients, clinicians face significant challenges in terms of selecting drugs for the treatment of depression. However, no previous studies have compared the efficacy of antidepressant treatments between psychiatrists with different levels of experience based on pharmacogenomics approach. Methods: A total of 178 patients were recruited and randomly assigned to pharmacogenomics-guided treatment group or regular treatment control group. The control group was further divided into the senior doctor and the nonsenior doctor subgroups. All participants completed pharmacogenomic assessments at baseline. They also completed the 17-items Hamilton Depression Scale (HAM-D Results: Compared with the control group, pharmacogenomics-guided group presented significant differences in DARS and ASEC scores at 32 weeks ( Conclusion: Pharmacogenomics-guided treatment can effectively mitigate the occurrence of anhedonia and side effects in patients with first-episode depression. Higher level of clinical experience among psychiatrists can lead to significant reduction in the frequency of antidepressant drug changes, and the depressive symptoms at the endpoint are negatively correlated with the clinicians' work experience. Pharmacogenomics may reduce the influence of clinical experience on treatment outcomes in primary mental healthcare settings.
