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

High nitrate concentrations in water present serious risks to human health. This study evaluates two removal strategies: layered double hydroxide (LDH) nanoparticles (NPs) and LDH-incorporated thin-film composite nanofiltration (TFC-NF) membranes to reduce nitrate concentration. First, Mg-Al, Ni-Fe, and Mn-impregnated Zn-Al LDH NPs were co-precipitated, characterized using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), Brunauer-Emmett-Teller (BET) analysis, field emission scanning electron microscopy (FESEM), and zeta potential measurement, and tested in batch adsorption experiments (20 mg/L nitrate solution, 1 g/L adsorbent dosage). Among the LDH NPs tested, Ni-Fe LDH demonstrated the highest nitrate rejection, achieving 13-14% at this concentration, with no significant change with further calcination. Next, the TFC-NF membranes were fabricated by embedding LDH NPs into the support layer; one variant received additional layer-by-layer (LBL) surface modification. The membranes were also characterized using FESEM and then evaluated using a 50 mg/L nitrate solution at 6 bar pressure and 25 °C. The TFC-NF membrane containing 0.25 wt% Mn-impregnated Zn-Al LDH achieved nitrate rejection of 43% with pure water flux (PWF) of 4.5 L/m
