Association between CYP2D6 genotype and treatment effectiveness and safety in 99 hospitalized patients with major depressive disorder a retrospective cohort study CYP2D6 genotype and antidepressant 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
Cytochrome P450 2D6 (CYP2D6) is a polymorphic enzyme that influences antidepressant metabolism. This retrospective cohort study investigated the association between CYP2D6 genotype and treatment outcomes in 99 hospitalized patients with major depressive disorder (MDD) in Belgrade, Serbia. Patients were classified as poor (PM, n = 5), intermediate (IM, n = 21), or normal metabolizers (NM, n = 73). Effectiveness and tolerability were assessed from admission to discharge (~4 weeks). Hamilton Depression Rating Scale (HAM-D) score reduction was the primary outcome; tolerability was measured using the Toronto Side Effects Scale (TSES). Compared with NMs, HAM-D score reductions were 4.3 and 9.0 points lower in IMs and PMs. TSES scores were 1.3 and 2.3 points higher in IMs and PMs, respectively. Central nervous system and gastrointestinal effects were more frequent in IMs and PMs; sexual dysfunction did not differ. Reduced CYP2D6 activity was associated with poorer outcomes, indicating the potential usefulness of CYP2D6 genotyping in MDD.
