Influence of the pre-operative time in upright sitting position and the needle type on the incidence of post-dural puncture headache (PDPH) in patients receiving a spinal saddle block for anorectal surgery.

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
backgroundA spinal saddle block can be a safe method for anorectal surgery with a low rate of complications when performed with the right technique. A dreaded complication is the post-dural puncture headache (PDPH), which can be decreased by the use of non-cutting spinal needles. Regrettably, cutting Quincke (Q)-type needles are still widely used for economic reasons. Besides size and design of a spinal needle, the pre-operative time in upright sitting position may also influence the incidence of PDPH after spinal saddle block.
methodsWithin 4 months, 363 patients undergoing anorectal surgery in saddle block technique were randomised to receive either a 27-gauge (G) pencil-point (PP) or a 27-G Q spinal needle and were pre-operatively left in upright sitting position for 10 or 30 min, respectively. The incidence of PDPH was assessed 1 week after the operation via a telephone interview.
resultsThree hundred sixty three patients (219 males/144 females) were analysed. Fifteen patients (4.1%) developed PDPH. Patients receiving spinal anaesthesia with a Q needle suffered significantly more frequently from PDPH [Q: n = 12 (6.6%) vs. PP: n = 3 (1.7%), p = 0.02], but there was no association between PDPH and pre-operative time in the upright position (p = 0.20).
conclusionsThese data prove that using 27-G PP needles is the method with the fewest side effects caused by spinal saddle block, and suggest that the time spent sitting in the upright position is not clinically relevant.
