Risk factors for early-onset hyperuricemia and gout following laparoscopic sleeve gastrectomy: a retrospective study.
Article in BMC surgery, 2025. 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
backgroundTo investigate the risk factors associated with early-onset hyperuricemia and gout attacks after Laparoscopic Sleeve Gastrectomy (LSG).
methodsA total of 535 obese patients who underwent LSG at Tianjin Medical University General Hospital between January 2022 and December 2024 were retrospectively enrolled according to predefined inclusion and exclusion criteria.Baseline and 1-month postoperative data—including demographic characteristics, body composition, and laboratory parameters—were collected to assess the incidence and risk factors of postoperative hyperuricemia and goutattacks.
results① The incidence of postoperative hyperuricemia was 65.79% (352/535), and the gout attack rate was 4.67% (25/535). The male-to-female ratio of gout patients was 19:6, with 7 patients having a history of gout.② Multivariate analysis revealed that male sex (OR = 7.360), younger age (OR = 0.97), higher preoperative uric acid level (OR = 1.007), lower preoperative creatinine level (OR = 0.934), and higher postoperative creatinine level (OR = 1.069) were independent risk factors for postoperative hyperuricemia. The predictive model demonstrated good performance (AUC = 0.802).③ Multivariate analysis revealed that male sex (OR = 9.434), history of gout (OR = 11.654), larger change amplitude in total body water percentage (OR = 1.193, ΔTBW%), and larger change amplitude in serum uric acid level (OR = 1.018, ΔSUA%) were independent risk factors for postoperative gout attacks. The predictive model demonstrated excellent performance (AUC = 0.895).
conclusionsThe incidence of early hyperuricemia after LSG is high, while the incidence of gout is relatively low. Patient sex, age, preoperativeserum uric acid, preoperative creatinine, and postoperative creatinine are independent risk factors for hyperuricemia after LSG. Patient history of gout, sex, and the amplitude of changes inTBW% and serum uric acid level are independent risk factors for gout attacks after LSG.
