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

This study assessed the effects of photobiomodulation (PBM) with 980 and 660 nm low-level diode laser on the expression of osteoprotegerin (OPG) and receptor activator of nuclear factor kappa-Β ligand (RANKL) genes by human periodontal ligament stem cells (PDLSCs) under static loading. In this in vitro study, cultured human PDLSCs were randomly assigned to 8 groups; of which, 7 groups underwent static loading (2 g/cm
