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
Backgroundsː The objective of this study was to assess the efficacy of gemcitabine as a treatment option for patients diagnosed with non-muscle invasive bladder cancer (NMIBC) who had previously experienced failure with Bacillus Calmette-Guerin (BCG) therapy in the last year.
methodsWe prospectively enrolled 28 patients with recurrent NMIBC after previous intravesical treatment in the last year who declined or were unsuitable for cystectomy between 2021 and 2023. Gemcitabine at 2,000 mg/100 mL was instilled weekly for 6 weeks. Patients were assessed for response after 8 weeks, with subsequent evaluations scheduled every three months to one year.
resultsThe findings demonstrated that out of the 28 patients, 20 (71.4%) exhibited a complete response to intravesical gemcitabine treatment, and 8 (28.6%) had no complete response. The average age of the participants was 60.25 years. The study identified significant differences in treatment response based on age but without significant differences based on gender. Furthermore, there was no noteworthy association between tumor stage and grade and treatment response. Moreover, among patients with low-grade tumors, 66.7% achieved a complete response, while 72.7% reached a complete response among those with high-grade tumors. Of the patients who reached a complete response, 28.6% experienced no recurrence during one year of follow-up, and 42.9% developed recurrent disease within one year of treatment initiation. Ten months following treatment, a patient developed muscle-invasive bladder cancer and went on to cystectomy.
conclusionIn conclusion, the results suggest that intravesical gemcitabine could represent a feasible choice for NMIBC patients unresponsive to BCG therapy and ineligible for or unwilling to undergo cystectomy.
