Extent of Pelvic Lymph Node Dissection at Partial Cystectomy: Effect on Cancer-Specific Mortality.
Article in International journal of urology : official journal of the Japanese Urological Association, 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
introductionWe assessed the extent of pelvic lymph node dissection (PLND) at partial cystectomy (PC) according to PC eligibility (≤cT2 stage, tumor ≤ 3 cm and segmental resection possible) and tested its effect on cancer-specific mortality (CSM).
methodsWithin the SEER database (2004-2021), we identified PC patients undergoing PLND and tabulated the number of lymph nodes (LNs) removed according to PC eligibility. Multivariable Cox-regression models tested the effect of PLND extent on CSM after adjusting for age, sex, T stage, N stage, and chemotherapy.
resultsOf 1017 PC patients undergoing PLND, 197 (19.4%) were eligible vs. 820 (80.6%) ineligible according to PC eligibility criteria. Median number of LNs removed at PLND was 6 (IQR: 3-11) in eligible versus 7 (IQR: 3-14) in ineligible patients (p = 0.09). Mean numbers of LNs removed at PLND increased over the study period, from 7 to 16 (p = 0.007) in PC-eligible and from 8 to 13 (p = 0.001) in PC-ineligible patients. In 1017 patients regardless of PC eligibility, 5-year CSM-free survival rate was 65.6%, and PLND extent predicted lower CSM (multivariable hazard ratio [mHR]: 0.99, p = 0.036). In 197 PC-eligible patients, 5-year CSM-free survival rate was 84.2%, and the PLND extent was not associated with CSM (mHR: 0.96, p = 0.2). Conversely, in 820 PC-ineligible patients, 5-year CSM-free survival rate was 61.1%, and PLND extent predicted lower CSM (mHR: 0.99, p = 0.043).
conclusionIn all PC patients regardless of eligibility status, more extensive PLND was associated with improved cancer-specific survival.
