Use of TaqMan array card to investigate bacterial isolates in diabetic foot ulcers.
Article in Journal of medical microbiology, 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
Diabetic foot disease is a major public health problem, with an annual National Health Service (NHS) expenditure exceeding £1 billion. Infection increases the risk of major amputation fivefold. Due to the polymicrobial nature of diabetic foot infections, it is often difficult to correctly and rapidly isolate pathological organisms with conventional culture techniques and deliver appropriate narrow-spectrum antimicrobials. Rapid DNA-based technology, using multi-channel arrays, offers a quicker alternative and has previously been used effectively in other settings. We undertook a prospective cohort study of deep tissue samples taken from diabetic foot ulcers (DFUs), comparing samples processed by conventional culture and real-time PCR TaqMan array card (TAC). Fifty samples were taken from 39 patients. The ulcers were of variable chronicity prior to sampling (range: 1-113 weeks) and were sited on the heel (3), midfoot (6) and forefoot (41). TAC results were available an average of 4.3 days earlier than culture results. Seventeen samples had the same organisms detected on culture and TAC. Sixteen of these 17 had additional organisms detected by TAC. The most frequent organisms detected by TAC that were not detected by culture were staphylococci,
