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

purposeThe purpose of this study was to compare oncologic outcomes between open nephroureterectomy (ONU) and laparoscopic nephroureterectomy (LNU) in patients with upper tract urothelial carcinoma. MATERIALS AND

methodsThe medical records of consecutive ONU and LNU cases from five tertiary institutions were retrospectively analyzed between 2000 and 2012. The propensity-score matching methodology was used to compare the two surgical approaches in terms of age, body mass index, American Society of Anesthesiologists score, tumor location, grade, pathologic T and N categories, the presence of lymphovascular invasion, and follow-up duration. The Kaplan-Meier with log-rank tests and clustered Cox regression were used to compare the estimated rates of survival for each surgical approach and to investigate the effect of the surgical approach on each prognostic outcome.

resultsSix hundred thirty-eight propensity-score matching pairs (n=1,276) were compared; LNU was significantly better than ONU in all types of survival, including intravesical recurrencefree survival (IVRFS), disease-free survival, overall survival (OS), and cancer-specific survival (CSS) (p < 0.05). The 3-year OS and CSS rates were significantly higher with LNU than with ONU (p < 0.05). Compared with ONU, LNU had significantly better 3-year OS and CSS rates (82.9% and 86.2% vs. 78.3% and 81.8%); there were no differences at 5 years. In subgroup analysis of the early-staged group, advanced-stage group, lymph node-positive group, and lymph node-negative group, the two approaches did not significantly affect prognostic outcomes, except LNU improved the IVRFS in the lymph node-negative or no history of previous bladder cancer group.

conclusionLNU had a significantly better prognostic outcome than ONU after propensity-score matching.
