Oculocardiac reflex in phacoemulsification: Peribulbar vs topical anesthesia.
Trial report in Indian journal of ophthalmology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Purpose: This study compares the vital parameters and pain experienced during phacoemulsification under peribulbar and topical anesthesia to determine the incidence of OCR. Methods: One hundred six patients are enrolled for phacoemulsification in a prospective and randomized study. Fifty-two patients undergo surgery in a peribulbar block (Group PB) and 54 in topical anesthesia (Group TA). Mean arterial pressure (MAP) and pulse rate are recorded during a preoperative check-up and at four other steps of surgery. Pain experienced during surgery and on a postoperative day, 5, is graded with a verbal analogue scale. OCR defined as a decrease in pulse rate by greater than 20% is calculated. Chi-square test, Fisher's exact test, paired t test and the comparison of means give the statistical analysis. A value of P < 0.05 was taken as significant. Results: MAP readings at baseline versus MAP at other steps of surgery show a trend towards rising with a P value of < 0.05 in both groups. Pulse rate measured at all steps of surgery versus baseline pulse rate in Group TA shows P < 0.05. OCR is present in nine patients in peribulbar block verses eleven patients in topical anesthesia with P value of 0.687. The pain scores using verbal analogue scale were higher in Group TA compared with Group PB with a P < 0.0001. Conclusion: Oculocardiac reflex can occur during phacoemulsification under both peribulbar block and topical anesthesia, and the difference is not significant.
