1 · What the graph read from it

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.

2 · The registry

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

aimsThis study aimed to assess the effects of low-dose tirzepatide combined with metformin (COM) versus metformin (MET) monotherapy in overweight/obese women with polycystic ovary syndrome (PCOS). MATERIALS AND

methodsSixty overweight/obese women with PCOS were randomised to the MET group (1000 mg twice daily [BID]) or the COM group (MET: 1000 mg BID, tirzepatide: 5 mg once weekly [QW]) for 16 weeks. The primary outcome was the change in body weight. Secondary outcomes included changes in anthropometric measures other than body weight, body composition, reproductive hormone levels, metabolic and endocrine parameters, inflammatory markers and menstrual cycle regularity. All outcomes were assessed at baseline and week 16. After week 16, participants were switched to MET monotherapy. Barrier contraception was required for 8 weeks and pregnancy outcomes were subsequently evaluated between weeks 25 and 48.

resultsAfter 16 weeks of treatment, compared with the MET group, the COM group resulted in greater reductions in weight (-1.7 ± 2.5 kg vs. -10.4 ± 3.5 kg; p < 0.001), body mass index (BMI) (-0.68 ± 1.82 vs. -4.12 ± 1.37 kg/m

conclusionsIn overweight/obese women with PCOS, low-dose tirzepatide combined with MET was associated with greater reductions in body weight and visceral fat, along with improvements in metabolic and reproductive outcomes compared with MET monotherapy.
