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
TiO2 nanoparticles are widely used in paints, plastics, cosmetics, printing ink, rubber, food products, pharmaceuticals and other products (photocatalyst, etc.). However, there is little toxicological information during reproduction and developmental period. This study was performed to obtain safety data for new TiO2 powder, GST (Green Sludge Titanium) produced through sludge recycling of the sewage treatment plant for Reproduction/developmental toxicity screening test in Sprague-Dawley (SD) rats in according to the OECD test guideline (TG 421). Based on the results of the dose-range finding study (14-day repeated toxicity), GST was orally administered to rats at doses of 0, 500, 1000, and 2000 mg/kg B.W/day. Males were dosed for 35 days beginning 14 days before mating, and females for a maximum of 53 days beginning 14 days before mating to day 13 of lactation, including throughout the mating, gestation and lactation periods. In the reproductive and developmental examinations, there were no marked toxicities in terms of general clinical signs, body weight, food consumption, organ weights, macroscopic / microscopic findings, stages of spermatogenesis in the testis, reproductive finding (estrous cycle, copulation-fertility-gestation index), developmental finding (number of corpora lutea and implantations, pups parameters including live birth and viability index). The NOAEL for reproductive/developmental screening toxicity was concluded to be 2000 mg/kg/day under the present study conditions.
