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
The present study was undertaken to evaluate the effect of L-arginine methyl ester (L-NAME), a nitric oxide synthase inhibitor on serum nitric oxide, progesterone, estradiol profiles and estrous cycle length in buffaloes. Murrah buffaloes (n = 16) exhibiting regular estrous cycles were randomly allocated to two groups of eight animals. In the treatment group, buffaloes were administered 400 mg/h L-NAME over 2 h (total dose = 800 mg) via the coccygeal artery and the aorta abdominalis on day 15 of the estrous cycle. In the control group, normal saline was infused on the same day of the cycle by the same route. Blood samples were collected every 4 h on days 15 and 16, and once daily from days 17 to 21 of the estrous cycle for the assay of progesterone, estradiol and nitric oxide. L-NAME treatment significantly (p < 0.05) reduced serum nitric oxide concentration from 4 h of day 15 until day 20 of the cycle. Serum progesterone concentration increased significantly (p < 0.05) between 0 and 20 h post treatment on day 15. The estrous cycle length was 19.8 ± 0.36 and 23.6 ± 0.17 days for control and treated group buffalo (p < 0.05), respectively. It was concluded that treatment of buffalo with L-NAME in the late luteal phase of the estrous cycle inhibited serum nitric oxide concentration resulting in increased progesterone production and extension of the effective life of the corpus luteum, thus prolonging the estrous cycle length.
