Parasitic contamination in green vegetables from open markets in Gampaha District, Sri Lanka: Implications for human health.

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
Intestinal parasitic infections in Sri Lanka have received little attention due to their perceived low prevalence. Consuming raw vegetables without proper washing is one of the main ways to transmit intestinal parasitic infections. Therefore, this study investigated the contamination of parasites in vegetables. A cross-sectional study was conducted from August 2023 to January 2024 at fifty selected open markets in ten cities (Ragama, Miriswatta, Kirillawala, Kadawatha, Balummahara, Kiribathgoda, Peliyagoda, Weliweriya, Imbulgoda and Gampaha) in Gampaha District, Sri Lanka. Four vegetable types, namely Centella asiatica (Gatu kola) [n = 162], Ipomoea aquatica (Kankun) [n = 150], Alternanthera sessilis (Mukunuwenna) [n = 160] and Lactuca sativa (Lettuce) [n = 148] that are consumed either raw or half cooked were selected. Approximately 50 g of each vegetable was taken randomly at each sampling attempt. Each sample was dipped in the Tween 20 (5%) in a shaker for 15 minutes, followed by sedimentation overnight and centrifugation (2000 × g for 15 min). Both supernatant and sediment were examined under a light microscope to detect parasitic stages. The overall prevalence of parasitic contamination in the samples was 21.29% (n = 132). Centella asiatica indicated the highest contamination (37.65% [61/162]). Lactuca sativa had the lowest contamination (2.02% [3/148]). Parasites including protozoan (Entamoeba histolytica, Giardia lamblia, Toxoplasma gondii, Blastocystis hominis, Paramphistomum spp and Balantidium coli) and helminths (Ascaris spp., Hymenolepis spp., Strongyloides stercoralis, Trichuris spp, Taenia spp, Toxocara canis and hookworms) were detected. Blastocystis hominis was the most predominant (4.68%; n = 29). Toxocara sp, G. lamblia and Eimeria sp were identified as least abundant (0.77%; n = 5). Every sample contained at least one parasitic contamination. A significant difference between the type of vegetables and the existence of parasites was identified (P = 0.008). The parasitic stages identified could cause infections among people with poor food hygienic/ preparation practices. Therefore, health authorities must educate consumers on precautionary measures to prevent re-emerging intestinal parasitic infections in Sri Lanka.
