Short-term impact of delayed surgical treatment on the prognosis of patients with T1bN1-stage PTC: a retrospective cohort study.
Article in BMC cancer, 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
backgroundAs the incidence of papillary thyroid carcinoma (PTC) increases, optimal timing for surgical interventions remains undefined. While surgical delays are known to affect prognosis adversely in various cancers, their impact on PTC is controversial.
methodsA retrospective study was conducted on 478 T1bN1-stage PTC patients treated at West China Hospital from January 2020 to May 2022. Patients underwent thyroidectomy with lymph node dissection and were categorized into three groups based on surgical delay: ≤90 days (group A, n = 264), > 90-180 days (group B, n = 92), and > 180 days (group C, n = 122). Additionally, patients were reclassified into two groups based on a one-year threshold: ≤365 days (group D, n = 420) and > 365 days (group E, n = 58). Tumor metastasis rates and postoperative complications were analyzed across these groups.
resultsThe median surgical delay was 79 days, and the median follow-up was 1362 days. Tumor metastasis occurred in 1.67% (8 patients), while postoperative complications occurred in 5.65% (27 patients). Metastasis rates were 1.89%, 1.09%, and 1.64%, and complication rates were 5.68%, 4.35%, and 6.56% for groups A, B, and C, respectively. No statistically significant differences were observed in metastasis or complication rates among the three groups. Similarly, no significant differences were found between groups D and E in tumor metastasis (p = 1.000) or complication rates (p = 0.555).
conclusionDelayed surgery was not associated with significantly increased short-term tumor metastasis or postoperative complication rates in patients with T1bN1-stage PTC.
