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

Urine pH is an important biomarker related to metabolic status and urinary system health, but reliable SERS quantification in real urine remains limited by matrix interference, heterogeneous hotspot distribution, and the narrow response range of single pH-responsive molecules. Here, we report a core-gap-shell Au@1,4-BDT@Au@4-MBA/MPY nanoprobe for ratiometric SERS detection of urine pH. 1,4-BDT was confined within the gap between the gold core and shell as an internal standard, while 4-MBA and 4-MPY were co-assembled on the outer gold shell to provide complementary protonation/deprotonation responses. The internal standard-corrected ratio I
