Response to febuxostat according to clinical subtypes of hyperuricemia: a prospective cohort study in primary gout.
Article in Arthritis research & therapy, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundWhile xanthine oxidase inhibitors target uric acid production, renal urate underexcretion is the predominant subtypes in gout. This study was to compare treatment response to the XOI febuxostat in a gout cohort according to clinical subtypes of hyperuricemia.
methodsA prospective cohort study was conducted to compare the efficacy and safety of febuxostat (initially 20 mg daily, escalating to 40 mg daily if not at target) in 644 gout patients with the three major clinical subtypes for 12 weeks. Hyperuricemia was defined as the renal overload subtype, the renal underexcretion subtype, or the combined subtype based on UUE > or ≤ 600 mg/d/1.73 m
resultsFewer participants with combined subtype achieved the SU target, 45.5% compared with 64.8% with overload subtype (P = 0.007), and 56.6% with underexcretion subtype (P = 0.022). More participants with combined subtype (82%) had febuxostat escalated to 40 mg than those with overload (62%, P = 0.001) or underexcretion subtype (68%, P = 0.001). In all participants, combined subtype hyperuricemia (OR = 0.64, 95%CI 0.41-0.99, P = 0.048) and baseline SU (OR = 0.74, 95%CI 0.62-0.89, P = 0.001) were independently associated with lower rates of achieving SU target.
conclusionsPeople with combined subtype have a lower response to febuxostat, compared to those with either overload or underexcretion subtype. Assessment of hyperuricemia subtype may provide useful clinical data in predicting febuxostat response.
