The Impact of Cilostazol in Refractory Vasospastic Angina.

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
introductionRefractory vasospastic angina (VSA) includes patients with disabling angina despite maximally tolerated calcium channel blocker and nitrate therapy. Randomised clinical trial evidence confirms the efficacy of cilostazol in refractory VSA, yet its use in real-world clinical practice is limited. This study evaluated the impact of cilostazol therapy on patient-reported outcomes in patients with refractory VSA.
methodsBetween June 2016 and May 2022, 15 consecutive refractory VSA patients were initiated on cilostazol (50 mg twice daily), with baseline and 3-month responses assessed via the Seattle Angina Questionnaire (SAQ). The primary outcome was a clinically significant reduction in angina frequency (i.e., >10-point improvement in SAQ angina frequency score) at 3 months.
resultsA clinically significant reduction in angina frequency was reported in 13 patients (86%) at 3 months, with 3 (20%) becoming angina free. Moreover, over 3 months, median SAQ scores improved for angina frequency (25 [IQR 15, 46] to 75 [30, 82]), physical limitation (53 [44, 67] to 83 [56, 92]), and quality of life (17 [4, 29] to 50 [35, 58]). Additionally, a 54% reduction in angina-related emergency department presentations and 50% reduction in angina-related hospital admissions were noted. Minor medication-related adverse effects were experienced by 3 patients, with no serious adverse effects noted. Cilostazol was continued in 14 patients (93%) beyond the 3-month follow-up period.
conclusionsIn patients with refractory VSA, cilostazol is well tolerated, improves patient-reported outcomes, reduces healthcare utilisation, and thus is an effective therapy in real-world clinical practice.
