Intraoperative robot telemetry and postoperative outcomes in robotic urologic surgery: a single-surgeon retrospective cohort study.
Article in Journal of robotic surgery, 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
Robotic systems record intraoperative telemetry, but its clinical utility is unclear. Associations between robot telemetry and postoperative length of stay (LOS) and hemoglobin drop (ΔHb) after robotic urologic surgery were evaluated in a retrospective analysis of consecutive single-surgeon robot-assisted procedures performed between 2 April 2024 and 22 December 2025. Telemetry metrics (instrument count, console time, instruments-active time) were linked to perioperative data and laboratory values. Associations were tested with Spearman correlations and multivariable regression for log-LOS adjusting for age, BMI, preoperative hemoglobin, creatinine, and procedure stratum; key analyses were repeated within radical prostatectomy and partial nephrectomy cohorts. The cohort comprised 100 procedures (median LOS 3 days (interquartile range [IQR] 3–4)). Instrument count correlated with LOS overall (ρ = 0.33, p = 0.00084) and within prostatectomy cases (ρ = 0.43, p = 0.0038). In the adjusted model (n = 68), each additional instrument was associated with longer LOS (β = 0.28; 95% confidence interval (CI) 0.09–0.47; exp[β] = 1.32). ΔHb was available in 70 cases (0.93 ± 0.62 mmol/L) and correlated weakly with console and instruments-active time (ρ = 0.26–0.27; p ≤ 0.03). Procedure type strongly influenced LOS; nevertheless, instrument count remained associated with LOS after adjustment, with the strongest signal in radical prostatectomy. Telemetry may provide an objective marker of intraoperative complexity and postoperative recovery, but procedure-specific validation is needed.
