Effect of metreleptin treatment in congenital generalized lipodystrophy: a retrospective analysis from the MENA region.
Observational study in Journal of endocrinological investigation, 2026. 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
purposeCongenital generalized lipodystrophy (CGL) is characterized by near-total loss of body fat, leptin deficiency, and severe metabolic complications. Clinical data show that metreleptin improves metabolic control in CGL; however, data from the Middle East and North Africa (MENA) is limited. We assessed the real-world effectiveness and safety of metreleptin in patients with CGL from this region.
methodsWe conducted a multicenter, retrospective chart review of patients with CGL. Baseline, 6 ± 2months (short-term), 2 ± 1years (long-term), and >3 years follow-up data were analyzed. Median changes from baseline were calculated for short- and long-term assessments; >3 years data were reviewed individually. Safety was evaluated up to 90 days after last dose.
resultsThirty-eight patients were included (82% female; median age at baseline, 6.3 years). Median treatment duration with metreleptin was 25 months (max dose, 10 mg/day). Significant short-term median reductions from baseline were observed for HbA1c (- 1.4%; n = 26), fasting plasma glucose (- 0.5 mmol/L; n = 21); fasting triglycerides (TG; -1.5 mmol/L; n = 26), alanine aminotransferase (- 18 IU/L, n = 27) and aspartate aminotransferase (- 7 IU/L, n = 27) (all p ≤ 0.02). These reductions were significant at long-term follow-up (p < 0.01) except for aspartate aminotransferase. At short-term follow-up, 50.0% of patients achieved ≥1% reduction in HbA1c and 65.4% had a ≥30% reduction in TG; corresponding long-term patient proportions were 46.7% and 61.5%. Most patients with >3 years follow-up showed improvement/maintenance of metabolic parameters. Overall, metreleptin was well tolerated with no new safety signals detected.
conclusionsOur findings support early intervention with metreleptin for sustained diabetes and hypertriglyceridemia control in CGL.
