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

objectivesTo compare the incidence of gout in individuals with diabetes receiving metformin vs sodium-glucose co-transporter-2 inhibitors (SGLT-2is).

methodsThis new-user comparative effectiveness study included adults from the JMDC claims database with health check-up and administrative claims data from 2014 to 2022. Individuals initiated on metformin were compared with those initiated on SGLT-2is. The primary outcome was the incidence of new gout diagnoses. After propensity-score inverse probability treatment weighting (IPTW), Cox proportional hazards models were fitted to estimate the hazard ratios (HRs) and 95% CIs. A linear mixed model was employed to assess the association between the two groups and changes in serum uric acid levels.

resultsA total of 21 561 individuals with diabetes were identified, including 17 636 males with a mean age of 53 years. The metformin and SGLT-2i groups included 13 535 and 8026 individuals, respectively. In the metformin and SGLT-2i groups, the gout incidence rates were 2.40 and 3.15 events per 1000 person-years, respectively. After IPTW, metformin was not associated with a decreased risk of gout compared with SGLT-2i (HR 0.90, 95% CI 0.63-1.28; rate difference -0.28, 95% CI -1.24 to 0.68 events per 1000 person-years). The mean difference in serum uric acid level change 1 year after the index date was 0.48 mg/dl (95% CI 0.43-0.52) for the metformin group relative to the SGLT-2i group.

conclusionGout risk may be comparable between metformin and SGLT-2is in individuals with diabetes, with metformin showing a lesser reduction in serum uric acid levels than SGLT-2is.
