Randomized control trial on effectiveness and safety of direct trocar versus Veress needle entry techniques in obese women during diagnostic laparoscopy.
Trial report in Archives of gynecology and obstetrics, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers, 2 of them syntheses that pooled it.
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
purposeTo determine the benefits and safety of direct trocar insertion versus Veress needle technique in obese women undertaking diagnostic laparoscopy procedures.
methodsRandomized-controlled trial on 135 obese women undergoing diagnostic laparoscopy and dye test for infertility was conducted. Women were randomly assigned to either direct trocar access (n = 68) or Veress needle access (n = 67) before achieving pneumoperitoneum. The same surgeon executed the laparoscopic techniques with a single-puncture technique. The primary outcome measures included total length of the procedure and incidence of any complications, while the mean laparoscopic entry time, volume of CO
resultsWomen in both groups had similar socio-demographic and clinical characteristics and none were lost to follow-up. The overall length of the procedure was significantly lesser in the direct trocar group compared to the Veress needle group (9.9 ± 6.0 vs 16.7 ± 4.7 min; p < 0.001). No significant differences occurred in other outcomes including mean entry time, volume of CO
conclusionsDirect trocar technique may be an effective alternative to Veress needle for pneumoperitoneum in obese women for diagnostic laparoscopy. It has a comparable rapid laparoscopic entry time but a significantly lower duration of the procedure and shorter exposure to anesthesia. Both methods are equally effective as there was no significant difference in the complications recorded. A greater sample trial may be essential for more corroborative substantiation. CLINICAL
