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

purposeTo evaluate oncologic parameters of men with bothersome LUTS undergoing surgical treatment with HoLEP or TURP.

methodsFive hundred and eighteen patients undergoing HoLEP (n = 289) or TURP (n = 229) were retrospectively analyzed for total PSA, prostate volume, PSA density, history of prostate biopsy, resected prostate weight, and histopathological features. Univariate and multivariate logistic regression models were used to identify independent predictors of incidental PCa (iPCa).

resultsMen undergoing HoLEP had a significantly higher total PSA (median 5.5 vs. 2.3 ng/mL) and prostate volume (median 80 vs. 41 cc), and displayed a greater reduction of prostate volume after surgery compared to TURP patients (median 71 vs. 50%; all p < 0.001). With a prevalence of incidental PCa (iPCa) of 15 and 17% for HoLEP and TURP, respectively, the choice of procedure had no influence on the detection of iPCa (p = 0.593). However, a higher rate of false-negative preoperative prostate biopsies was noted among iPCa patients in the HoLEP arm (40 vs. 8%, p = 0.007). In multivariate logistic regression, we identified patient age (OR 1.04; 95% CI 1.01-1.07, p = 0.013) and PSA density (OR 2.13; 95% CI 1.09-4.18, p = 0.028) as independent predictors for the detection of iPCa.

conclusionsDespite differences in oncologic parameters, the choice of technique had no influence on the detection of iPCa. Increased patient age and higher PSA density were associated with iPCa. A higher rate of false-negative preoperative prostate biopsies was noted in HoLEP patients. Therefore, diagnostic assessment of LUTS patients requires a more adapted approach to exclude malignancy, especially in those with larger prostates.
