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 compare thulium laser incision of prostate (ThuIP) versus water vapor thermal therapy (Rezum) in the treatment of benign prostatic obstruction (BPO) with ejaculation-sparing intent in a retrospective analysis of cohorts treated at different institutions and during different time intervals.
methodsData of patients who underwent surgery for BPO were retrospectively collected and analyzed from two independent cohorts. The ThuIP cohort corresponds to a previously published single-arm series and included selective vaporesection of the median lobe when obstructing (27%). The comparative study design was conceived a posteriori, and only patients with complete 12-month follow-up were included. Pre, intra, and post-operative data were compared. Functional and patient-reported outcomes were compared at 6 and 12 months follow-up.
results120 and 81 patients underwent ThuIP and Rezum, respectively. Operative time (15 vs 10 min, p < 0.001) and LOS (3 vs 2 days, p < 0.001) were longer for ThuIP, while Rezum showed a prolonged catheterization time (2 vs 7 days, p < 0.001). Rezum was associated with a higher percentage of transient acute urinary retention (3.4% vs 13.6%, p = 0.006). One patient in the ThuIP group developed a Clavien-Dindo grade IIIa complication. ∆IPSS favored ThuIP during follow-up (p < 0.001 and p = 0.001 at 6 and 12 months, respectively), while ∆Q
conclusionsThuIP and Rezum are viable alternatives for achieving de-obstruction with a high chance of ejaculation preservation; in this retrospective comparison of cohorts treated in different settings, ThuIP provides higher improvement in patient-reported outcomes and faster improvement in functional outcomes, while Rezum appears to be a slightly faster and less invasive procedure.
