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.
Compared to metformin alone, the combination of liraglutide and metformin significantly improved glycaemic metabolism: FPG (standard mean difference = -1.92, 95% confidence interval [CI] [-2.43, -1.41]; I CONCLUSION: The combination of liraglutide and metformin resulted in greater improvements in body weight, blood sugar levels, insulin sensitivity, hormone balance (including LH, FSH and testosterone) and cholesterol profiles.

What it adds to each cell
For every cell the paper feeds: the belief in the claim with and without this paper, and this paper's estimate drawn against every other readable study in the cell. The ringed dot is this paper.

This paper's own estimate is on a different scale from the rest of the cell, so it is not drawn here.

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
The marked sentences are the ones the graph read a number from.
purposeOverweight or obese women with polycystic ovary syndrome (PCOS) often experience significant metabolic and hormonal disturbances. This systematic review and meta-analysis evaluated whether liraglutide combined with metformin is more effective than metformin alone in improving glycaemic control, lipid metabolism, body mass index (BMI) and sex hormone profiles in this population.
methodsWe systematically searched PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure, Weipu, SinoMed and Wanfang Data for randomised controlled trials (RCTs) comparing liraglutide plus metformin to metformin monotherapy in overweight or obese women with PCOS. Primary outcomes included fasting plasma glucose (FPG), 2-h postprandial glucose, HbA1c, fasting insulin, homeostasis model assessment of insulin resistance (HOMA-IR), BMI, sex hormones (luteinising hormone [LH], follicle-stimulating hormone [FSH], total testosterone [TT]) and lipid profiles (total cholesterol [TC], triglycerides [TG], low-density lipoprotein cholesterol [LDL-C] and high-density lipoprotein cholesterol [HDL-C]). Subgroup analyses were conducted by treatment duration, lifestyle intervention and baseline BMI.
resultsA total of 19 RCTs involving 1657 women with PCOS were included. Compared to metformin alone, the combination of liraglutide and metformin significantly improved glycaemic metabolism: FPG (standard mean difference = -1.92, 95% confidence interval [CI] [-2.43, -1.41]; I
conclusionThe combination of liraglutide and metformin resulted in greater improvements in body weight, blood sugar levels, insulin sensitivity, hormone balance (including LH, FSH and testosterone) and cholesterol profiles. These findings indicate that the combined therapy offers more comprehensive metabolic and hormonal benefits than metformin alone for women with PCOS.
