Sustained Metabolic Improvements with Low-Dose Metformin Combined with Oral Contraceptives in Female Adolescents with PCOS: A Single-Center Retrospective Cohort Study.

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
introductionThis study aimed to evaluate metformin treatment's immediate and long-term efficacy in adolescent patients with polycystic ovary syndrome (PCOS) and hyperinsulinemia and the subsequent metabolic evolution post-treatment discontinuation.
methodsThis single-center, retrospective cohort study included 168 adolescent girls (12-17 years) diagnosed with PCOS between December 2018 and August 2024. All participants underwent an oral glucose tolerance test to evaluate insulin sensitivity and were stratified into two groups: patients with normal insulinemia (n = 21) and patients with hyperinsulinemia (n = 147). Patients with hyperinsulinemia were offered low-dose metformin (500 mg twice daily); 80 accepted and formed the treatment arm, while 53 declined and served as controls. Simultaneously, every subject received a continuous regimen of combined oral contraceptives (COCs) (30 µg ethinyl estradiol/3 mg drospirenone). Clinical, biochemical, and ultrasound assessments were conducted at baseline, at regular intervals during therapy, at the end of treatment, and at least 24 months after metformin discontinuation to evaluate immediate and long-term outcomes.
resultsMetformin therapy yielded favorable body mass index, insulin sensitivity, and androgenic profile outcomes. Remarkably, these benefits persisted beyond the cessation of treatment. Metformin responders showed a ≥ 20% decrease in the insulin area under the curve values post-treatment. Our investigation revealed a substantial reduction in insulin resistance indices, evident both after therapy (p < 0.001) and during post-therapy follow-up (p = 0.001) compared to baseline values. Furthermore, patients showed improvements in clinical hyperandrogenism and reductions in ovarian volume.
conclusionsOur study highlights the effectiveness of low-dose metformin therapy in improving insulin resistance and metabolic parameters among adolescent patients with PCOS. Sustained benefits were observed even after treatment cessation. These findings underscore the potential for early intervention with metformin during adolescence to confer long-lasting advantages in managing metabolic abnormalities associated with PCOS.
