Method: Roster covers 12 continuous glucose monitors (CGMs) spanning the three segments a 2026 buyer compares: prescription/insulin-integrated CGMs (Dexcom G6, Dexcom G7, Abbott FreeStyle Libre 2 Plus, Abbott FreeStyle Libre 3, Abbott FreeStyle Libre 3 Plus, Medtronic Guardian 4, Medtronic Simplera Sync), long-wear implantable CGMs (Senseonics Eversense E3, Senseonics Eversense 365), and over-the-counter wellness biosensors (Dexcom Stelo, Abbott Lingo, Sibionics GS3). All 9 seed products were kept and verified; three were added to round out the comparison: FreeStyle Libre 3 (the base 14-day model still actively dispensed in the US alongside Libre 3 Plus), Medtronic Simplera Sync (the 2025 disposable successor that now pairs with the MiniMed 780G, positioned alongside Guardian 4), and Eversense 365 (Senseonics' newer 1-year implant, now sold alongside the 6-month E3). Abbott Libre Rio was researched and deliberately excluded: it was FDA-cleared in June 2024, but per Abbott's own newsroom and every trade source checked on 2026-08-01 it still has not commercially launched in the US, so no verifiable specs or price exist for it — including a product buyers cannot yet purchase would mean an entry that is mostly null. Primary spec source for the Dexcom / Abbott / Medtronic / Senseonics prescription and implantable devices is the American Diabetes Association's consumerguide.diabetes.org CGM comparison database, which tabulates wear duration, warmup time, MARD, sensor size and water resistance in a consistent format across manufacturers; official manufacturer sites (stelo.com, hellolingo.com, sibionicscgm.com, medtronicdiabetes.com/minimed.com) filled gaps and confirmed OTC-vs-prescription status. No manufacturer publishes a direct-to-consumer USD MSRP for prescription/DME-channel sensors (Dexcom G6/G7, the Libre family, Guardian 4, Simplera Sync, Eversense E3/365) since they are billed through pharmacy or durable-medical-equipment channels; for those, priceUsd uses SingleCare's published average US pharmacy cash price without insurance for the smallest standard fill (clearly flagged as such in priceNote) — these are real observed market prices, not manufacturer list prices, and they vary by pharmacy and region. Sibionics GS3 has no FDA clearance and is not officially sold in the US (its storefront defaults to a EUR-priced European store, confirmed 2026-08-01); priceUsd is null rather than guessed from grey-market resellers. mard_accuracy_pct records each source's reported adult MARD; pediatric figures, where a source states one separately, are noted in that product's provenance. Wikimedia Commons was searched first for every product; where a correctly-identified CC-licensed photo existed it was used (Dexcom G6, Dexcom G7, FreeStyle Libre 2 Plus, FreeStyle Libre 3, FreeStyle Libre 3 Plus). Where Commons had nothing, an official manufacturer or manufacturer-supplied retailer product photo was used instead and marked with a '© Brand' license (Dexcom Stelo, Abbott Lingo, Medtronic Guardian 4, Medtronic Simplera Sync, Sibionics GS3). No freely-licensed photo could be confirmed for Senseonics Eversense E3 or Eversense 365 after checking Wikimedia Commons, Wikipedia, eversensecgm.com, and PR Newswire/BusinessWire press-kit pages, so the image field is omitted for both rather than guessed.
