Association between postoperative surgical site infection and oncologic outcomes in soft tissue sarcoma: a propensity score-matched analysis using the bone and soft tissue registry.
Article in International orthopaedics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
purposePostoperative surgical site infection (SSI) is a prevalent complication. The impact of SSI on oncologic outcomes in soft tissue sarcoma (STS) remains debatable. This study evaluates the correlation between SSI and prognosis following STS resection through analysis of a national registry and propensity score matching (PSM).
methodsWe conducted a retrospective cohort study using data from the Japanese Nationwide Bone and Soft Tissue Tumor (BSTT) Registry between 2006 and 2019. The study included patients aged 18 years or older with localized primary STS who underwent surgical resection. PSM at a 1:3 ratio was performed using 11 baseline variables to ensure balance in patient and tumour characteristics between the SSI and non-SSI groups. The overall survival (OS), local recurrence-free survival (LRFS), and distant metastasis-free survival (DMFS) were analyzed using the Kaplan-Meier method and compared using the log-rank test.
resultsA total of 6,303 patients met the inclusion criteria, of whom 226 (3.6%) developed SSI. Prior to matching, the SSI group exhibited significantly poorer OS (5-year rate: 74.0% vs. 80.0%, p = 0.044) and DMFS (5-year rate: 63.1% vs. 72.4%, p = 0.02). Following PSM, 221 matched pairs (n = 884) were analyzed, and no significant differences in OS (p = 0.53) and DMFS (p = 0.19) were observed between the SSI and non-SSI groups.
conclusionsPostoperative SSIs were not significantly associated with oncologic outcomes after adjusting for confounding factors. These findings suggest that SSI may not be an independent prognostic factor in patients with STS.
