The diagnostic value of urine heat shock protein 70 and prostatic exosomal protein in chronic prostatitis.
Article in Journal of clinical laboratory analysis, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo explore the diagnostic value of the levels of prostatic exosomal protein (PSEP) and heat shock protein 70 (HSP70) in the urine of patients with chronic prostatitis (CP).
methodUrine samples from 210 CP patients (70 cases of the USA National Institutes of Health Category II [NIH-II], 70 NIH-IIIa, and 70 NIH-IIIb patients) and 70 control subjects were collected between May 2018 and February 2020. The levels of PSEP and HSP70 in urine were detected by enzyme-linked immunosorbent assay. The differences in urine PSEP and HSP70 levels between the groups were analyzed, and receiver operating characteristic (ROC) curves were used to analyze the clinical value of PSEP and HSP70 in the diagnosis of CP.
resultsThe PSEP levels of CP patients were significantly higher than those of the control group (p < 0.001), but there was no difference in PSEP levels among CP subgroups. The level of HSP70 in the urine of the NIH-II patients was significantly lower than the levels in the NIH-IIIa and NIH-IIIb subgroups and the control group, but there was no difference in HSP70 levels between the NIH-IIIa and NIH-IIIb subgroups and the control group. ROC curve analysis results showed that the area under the curve (AUC) of PSEP for the NIH-II, NIH-IIIa, and NIH-IIIb patients was 0.751, 0.776, and 0.731, respectively. The AUC of HSP70 in NIH-II patients was 0.784, and the AUC of combined detection of PSEP and HSP70 in NIH-II patients was 0.858.
conclusionUrine PSEP can be used as a marker for the diagnosis of CP, but it cannot distinguish between the various types of CP, and HSP70 can be used as a diagnostic index for NIH-II classification.
