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

objectiveTo evaluate whether the modified G8 (mG8) screening tool predicts severe postoperative complications and 90-day mortality in patients undergoing robot-assisted radical cystectomy (RARC).

methodsWe performed a single centre retrospective cohort study of patients who underwent RARC with ileal conduit or orthotopic neobladder diversion between 2011 and 2020 at a tertiary centre. Preoperative frailty was assessed using the mG8 score. Severe complications were defined as Clavien–Dindo grade ≥ 3. Univariable and multivariable logistic regression analyses were performed to evaluate the association of the mG8 score with severe complications and 90-day mortality.

resultsA total of 155 patients were included. The median age was 69 years, and 49 patients (31.6%) had an impaired mG8 score (≥ 6). Severe complications occurred in 67 patients (43.2%), and 90-day mortality occurred in 10 patients (6.5%). In univariable analysis, an impaired mG8 score was significantly associated with severe complications (OR 2.94, 95% CI 1.46–5.93, p = 0.002). After adjusting for age group, the mG8 score remained an independent predictor (OR 2.65, 95% CI 1.29–5.45, p = 0.008). An impaired mG8 score was also associated with increased 90-day mortality (OR 5.72, 95% CI 1.46–22.81, p = 0.015). Age ≥ 76 years predicted higher mortality in univariable analysis but was not associated with severe complications in adjusted models.

conclusionThe mG8 screening tool is a promising predictor of major postoperative complications and 90-day mortality following RARC. Frailty, rather than chronological age or comorbidity burden, appears to better identify high-risk patients. Prospective multicentre studies are warranted to validate the role of the mG8 score in preoperative risk stratification for radical cystectomy.
