1 · What the graph read from it

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.

2 · The registry

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

purposeLaparoscopic radical nephroureterectomy (LNU) has gradually become the new standard treatment for localized upper tract urothelial cancer (UTUC). With more blunt dissection and tactile sensation, hand-assisted LNU might shorten the operative time compared with the pure laparoscopic approach. However, whether the use of the hand-assisted or the pure laparoscopic approach has an effect on oncological outcomes remains unclear.

methodsWe retrospectively identified 629 patients with non-metastatic UTUC who underwent hand-assisted (n = 515) or pure LNU (n = 114) at 9 hospitals in Taiwan between 2004 and 2019. Overall survival, cancer-specific survival, recurrence-free survival, and bladder recurrence-free survival were compared between these two groups using inverse-probability of treatment weighting (IPTW) derived from the propensity scores for baseline covariate adjustment.

resultsThe median follow-up period was 32.9 and 28.7 months in the hand-assisted and the pure groups, respectively. IPTW-adjusted Cox proportional hazards models showed that the laparoscopic approach (pure vs. hand-assisted) was not significantly associated with all-cause mortality (HR 0.79, 95% CI 0.49-1.24, p = 0.304), cancer-specific mortality (HR 0.88, 95% CI 0.51-1.51, p = 0.634), or extra-vesical recurrence (HR 0.65, 95% CI 0.41-1.04, p = 0.071). However, the pure laparoscopic approach was significantly associated with lower intra-vescial recurrence (HR 0.64, 95% CI 0.43-0.96, p = 0.029) for patients who underwent LNU. Kaplan-Meier curves also revealed that the pure laparoscopic approach was associated with better bladder recurrence-free survival compared with the hand-assisted laparoscopic approach in both the original cohort and the IPTW-adjusted cohort (log-rank p = 0.042 and 0.027, respectively).

conclusionsThe performance of hand-assisted or pure LNU does not significantly affect the all-cause mortality, cancer-specific mortality, or extra-vesical recurrence for patients with non-metastatic UTUC. However, the hand-assisted laparoscopic approach could increase the risk of intra-vesical recurrence for patients who undergo LNU.
