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

purposeInterstitial cystitis/bladder pain syndrome (IC/BPS) is a complex chronic condition characterized by bladder pain and urinary symptoms. Functional bladder capacity (FBC) in daily life, cystometric bladder capacity (CBC) during urodynamic studies, and maximum bladder capacity (MBC) under anesthesia have distinct clinical implications for diagnosing and prognosing patients with IC/BPS. This study aims to assess the role of bladder capacity measurements in evaluating these patients.

methodsWe conducted a retrospective cohort study involving 198 patients with IC/BPS without Hunner’s lesions treated with intravesical platelet-rich plasma (PRP) injections. Bladder capacity was assessed by: FBC via three-day voiding diary, CBC via videourodynamics, and MBC via cystoscopic hydrodistention under anesthesia. We used Pearson correlations and multiple linear regression analyses to examine the association of bladder capacity measurements with IC symptom severity and PRP treatment outcomes (GRA).

resultsFBC significantly correlated with MBC (r = 0.301, p < 0.01), symptom severity (ICSI: r = − 0.360, p < 0.01), and treatment outcome (GRA at 6 months: r = 0.251, p < 0.01). Multiple regression analysis revealed that sensation of a full bladder (β = 0.357, p = 0.044), MBC (β = 0.292, p = 0.004), and GRA (β = 0.189, p = 0.044) were significantly associated with FBC.

conclusionFBC is a clinically relevant measure of bladder condition and symptom burden in IC/BPS, demonstrating strong associations with MBC and treatment outcomes. Given its non-invasive nature and ease of measurement, FBC should be considered the primary assessment tool for IC/BPS among these capacity measures.
