Effects of excessive tea consumption on pregnancy weight gain and neonatal birth weight.
Article in Obstetrics & gynecology science, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
objectiveTea lovers are increasing worldwide. We hope that this report is the first to discuss the possible impacts of high black tea consumption on gestational weight gain (GWG) and birth parameters.
methodsThroughout one year, a total of 7,063 pregnant ladies coming for first antenatal visit were screened in a major tertiary center. Of them, 1,138 were involved and divided according to their preference into 3 groups: excessive tea (ET), usual tea (UT), and mixed beverages group. The study included women who gave birth to healthy neonates.
resultsThe rate of ET consumption was 4.13% with a total of 41 cases. The UT group (controls) comprised 94 women. ET was significantly associated (P<0.05) with maternal age, parity, occupation, smoking, and poor GWG starting from 30 weeks' gestation until delivery, low birth weight, and small for gestational age (SGA). Poor GWG had a higher relative risk (with 95% confidence interval) in the ET group than in the UT group in crude (1.84 [0.85-2.43]) and risk adjusted models (1.25 [0.28-2.26]). Further, similar results were obtained for SGA in the crude and 3 adjusted models, where the first model was adjusted for bio-obstetrical variables, the second for social parameters, and the third for all factors included in the previous models (1.53 [0.62-2.81], 1.52 [0.71-2.50], and 1.46 [0.78-2.39]), respectively.
conclusionConsumption of large amounts of daily black tea during pregnancy (≥1,500 mL) is a significant cause of poor GWG and SGA.
