Circadian changes in cockroach ommatidial structure.
Article in Journal of comparative physiology. A, Sensory, neural, and behavioral physiology, 1993. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
1. Morphological correlates of circadian changes in eye sensitivity to light measured electrophysiologically were sought in the cockroach, Leucophaea maderae. Cross sections of ommatidia removed at subjective midday and subjective midnight on 3 successive days from roaches held under constant darkness (DD) at 25 +/- 2 degrees C were examined using a transmission electron microscope for morphological differences related to sampling time. 2. The temporal difference in submicrovillar cisternae (SMC) area appeared to exhibit a circadian rhythm, however, the amplitude of this temporal difference measured under DD was less than that observed under LD 12:12 conditions. SMC areas characteristic at nighttime were achieved at subjective midnights but the area diminished only partially toward the daytime state on subjective middays. 3. Rhabdom area remained constant and the daily rhythm of screening pigment granules (SPG) arrangement about the rhabdom was not observed under conditions of constant darkness. 4. Results of this study indicate that a pacemaker(s) actively influences the change in the SMC toward the nighttime state, whereas, the change toward the daytime state results from a passive mechanism that possibly could be accelerated by light.
