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

Objective: To investigate whether storage or voiding symptoms respond more favourably to the use of Kranus Lutera, the first app-based digital therapeutic for male lower urinary tract symptoms (LUTS), using detailed item-level analysis of the IPSS questionnaire. Materials and Methods: The present data represent a post-hoc analysis of the results of the BEST trial, a randomized controlled study evaluating the efficiency of the digital therapy Kranus Lutera. The study period lasted 12 weeks, conducted between 04/2023 and 11/2023. We assessed the mean change from baseline to 12 weeks for each of the seven IPSS items. Voiding symptoms (items 1, 3, 5 and 6) and storage symptoms (items 2, 4 and 7) were analysed separately. Results: Participants using the digital therapeutic demonstrated statistically significant improvements across all IPSS items. Compared to the control group, the intervention group showed a significant and clinically relevant improvement in the primary endpoint (IPSS), with an overall reduction of -7.0 points (95% CI: -8.1 to -5.9, p < 0.0001). Notably, improvements in storage symptoms were consistently larger than those in voiding symptoms. The analysis of individual IPSS questions showed the greatest changes in the overall cohort for questions 1, 2 and 7 (each p < 0.0001). Patients with the single diagnosis BPH (N40) showed the greatest score reduction in questions 2 and 5 (each p < 0.0001), patients with OAB (N32.8) in questions 2, 4 and 7 (each p < 0.0001) and patients with BPH and OAB (N40 + N32.8) in questions 2, 3 and 7 (question 2 and 3 p < 0.0001, question 7 p = 0.0015). According to the analysis of individual IPSS questions, the greatest improvements were observed in frequency, nocturia and the feeling of incomplete bladder emptying. Conclusion: These findings suggest that a structured app-based therapeutic may exert a stronger effect on storage symptoms than voiding symptoms in men with LUTS. This study confirms the value of the digital therapy as an integral part of the standard care for patients with male LUTS.
