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

To investigate the effect of phenolic hydroxyl group number on the interaction between catechins and a plant-derived protein carrier, four catechins with varying hydroxyl numbers-epicatechin (EC), epicatechin gallate (ECG), epigallocatechin (EGC), and epigallocatechin gallate (EGCG)-were investigated. The new plant-derived edible dock protein (EDP) was selected as a carrier matrix. EDP, when employed as a protein delivery carrier, possessed a hydrophobic amino acid content of 45%. This structural feature enabled it to provide more hydrophobic cavities for small molecule compounds, thereby facilitating better binding with them. The results indicated that the order of loading capacity of catechins within EDP was EGCG (9.7%) > ECG (9.1%) > EGC (8.8%) > EC (7.1%). This sequence was consistent with the number of hydroxyl groups in catechin: EGCG (8) > ECG (7) > EGC (6) > EC (5). Among the four catechins, EGCG had the highest binding constant (Ka = 2.6 × 10
