Impact of delay in cystoscopic surveillance on recurrence and progression rates in patients with non-muscle-invasive bladder cancer during the COVID-19 pandemic.
Article in International journal of clinical practice, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 papers.
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
purposeTo evaluate the impact of delay in cystoscopic surveillance on recurrence and progression rates in non-muscle-invasive bladder cancer (NMIBC). MATERIALS AND
methodsA total of 407 patients from four high-volume centres with NMIBC that applied for follow-up cystoscopy were included in our study prospectively. Patients' demographics and previous tumour characteristics, the presence of tumour in follow-up cystoscopy, the pathology results of the latest transurethral resection of bladder tumour (if tumour was detected) and the delay in cystoscopy time were recorded. Our primary outcomes were tumour recurrences detected by follow-up cystoscopy and progression. Multivariate logistic regression analysis was performed using the possible factors identified with univariate analyses (P values ≤ .2).
resultsA total of 105 patients (25.8%) had tumour recurrence in follow-up cystoscopy, and 20 (5.1%) of these patients had disease progression according to grade or stage. In multivariate analysis, the number of recurrences (OR: 1.307, P < .001) and the cystoscopy delay time (62-147 days, OR: 2.424, P = .002; >147 days, OR: 4.883, P < .001) were significant risk factors for tumour recurrence on follow-up cystoscopy; the number of recurrences (OR: 1.255, P = .024) and cystoscopy delay time (>90 days, OR: 6.704, P = .002) were significant risk factors for tumour progression.
conclusionsThis study showed that a 2-5 months of delay in follow-up cystoscopy increases the risk of recurrence by 2.4-fold, and delay in cystoscopy for more than 3 months increases the probability of progression by 6.7-fold. We suggest that cystoscopic surveillance should be done during the COVID-19 pandemic according to the schedule set by relevant guidelines.
